Zopiclone 7.5mg Blue

1. What is Zopiclone? A Clinical Definition

Zopiclone is a hypnotic (sleep-inducing) agent prescribed for the short-term management of severe insomnia. It belongs to a class of drugs known as cyclopyrrolones and is often sold under brand names such as Zimovane and Imovane. While its primary function is as a hypnotic, Zopiclone also exhibits anxiolytic (anti-anxiety), anticonvulsant, and myorelaxant (muscle-relaxant) properties.

Its licensed indication in the United Kingdom is strictly for the treatment of insomnia that is debilitating or causing the patient extreme distress. The therapeutic goal is to help individuals fall asleep more quickly, reduce night-time awakenings, and improve overall sleep duration and quality. It is critical to understand that Zopiclone is intended as a temporary solution to be used for the shortest possible duration, not as a long-term cure for chronic sleep problems.

1.2 The ‘Z-Drug’ Classification: Comparison with Benzodiazepines

Zopiclone is one of the three medications commonly referred to as ‘Z-drugs’, alongside zolpidem and zaleplon. This classification stems from the fact that their generic names begin with the letter ‘Z’. Although Zopiclone is molecularly and structurally distinct from the benzodiazepine class of drugs (e.g., diazepam, lorazepam), its pharmacological effects and mechanism of action are remarkably similar.

Z-drugs were developed with the objective of providing the sedative effects of benzodiazepines while potentially reducing some of their well-documented adverse effects, such as dependence, tolerance, and disruption of natural sleep architecture. However, extensive clinical experience and research have demonstrated that these risks, while perhaps marginally different, remain highly significant with Zopiclone. A meta-analysis of randomised controlled trials found few clear and consistent differences between Zopiclone and benzodiazepines regarding key sleep metrics like sleep onset latency and total sleep duration. Therefore, it should be regarded with a similar level of caution as traditional benzodiazepines.

1.3 Crucial Legal Context: Zopiclone as a Class C Controlled Substance in the UK

It is of paramount importance to understand the legal status of Zopiclone in the United Kingdom. Following recommendations from the Advisory Council on the Misuse of Drugs (ACMD), Zopiclone was classified as a Class C drug under the Misuse of Drugs Act 1971. This legislation provides the legal framework for controlling substances that are deemed “dangerous or otherwise harmful,” with Class C representing a significant level of potential harm.

The decision to control Zopiclone was based on its chemical similarity and comparable effects to benzodiazepines and zolpidem, which are also Class C drugs. The ACMD concluded that the potential for social harm arising from the misuse of Zopiclone was similar to that of other controlled sedatives. Harms associated with its misuse include the risk of coma, respiratory depression, and death, particularly when taken in excessive doses or combined with other central nervous system (CNS) depressants like alcohol.

This classification means that possession of Zopiclone without a valid prescription is unlawful in the UK. Its supply is tightly regulated under the Misuse of Drugs Regulations 2001, which govern its legitimate use in medicine and require strict protocols for storage and record-keeping in clinical environments. This legal framework underscores the serious risks associated with the unsupervised use of this medication.

Section 2: The Scientific Basis of Zopiclone’s Action

2.1 Mechanism of Action: Enhancing GABAergic Inhibition

Zopiclone exerts its sedative effects by modulating the activity of the central nervous system (CNS). Its primary mechanism of action involves enhancing the effects of gamma-aminobutyric acid (GABA), which is the main inhibitory neurotransmitter in the human brain. GABA’s natural function is to reduce neuronal excitability, thereby producing a calming effect.

Zopiclone is classified as a positive allosteric modulator of the GABA_A receptor. Although it is not a benzodiazepine, it binds to the same benzodiazepine recognition site on the GABA_A receptor complex. This binding action does not activate the receptor directly; instead, it increases the affinity of GABA for its own binding site. This potentiation of GABA’s natural effect leads to an increased frequency of chloride ion channel openings. The resulting influx of negatively charged chloride ions into the neuron causes hyperpolarization of the cell membrane, making it less likely to fire an action potential. This widespread neuronal inhibition throughout the CNS manifests as sedation, hypnosis (sleep), and anxiolysis.

Zopiclone acts as a full agonist at various GABA_A receptor subtypes, including α1, α2, α3, and α5, demonstrating a lack of selectivity that is similar to most benzodiazepines. This broad action is responsible for its range of therapeutic effects as well as some of its adverse effects.

2.2 Pharmacokinetics: The Lifecycle of Zopiclone in the Body

The pharmacokinetic profile of a drug describes its journey through the body, encompassing absorption, distribution, metabolism, and excretion. Understanding this profile is essential for its safe and effective use.

• Absorption and Onset of Action: Following oral administration, Zopiclone is absorbed rapidly, with an onset of action typically occurring within one hour. It has a high bioavailability of approximately 75-80%, meaning a large proportion of the dose reaches the systemic circulation. The presence of a high-fat meal prior to administration does not affect the total amount of drug absorbed but can delay the time it takes to reach peak plasma concentration, which may delay the onset of sleep.
• Distribution and Protein Binding: Zopiclone is widely distributed throughout the body’s tissues, readily crossing the blood-brain barrier to exert its effects on the CNS. It has a moderate degree of plasma protein binding, reported to be between 45% and 80%.
• Metabolism: The drug is extensively metabolized in the liver before it can be eliminated from the body. The primary metabolic pathways involve the cytochrome P450 (CYP) enzyme system, specifically the enzymes CYP3A4 and CYP2E1. This metabolic process produces two main metabolites: an N-oxide derivative, which has weak pharmacological activity, and an N-desmethyl metabolite, which is inactive. The heavy reliance on the CYP3A4 enzyme is a critical clinical consideration, as it is the source of numerous significant drug-drug interactions.
• Elimination and Half-Life: The metabolites of Zopiclone are primarily excreted from the body via the kidneys in urine (approximately 80%). The terminal elimination half-life—the time it takes for the concentration of the drug in the plasma to reduce by half—is approximately 5 hours (with a range of 3.5 to 6.5 hours) in healthy young adults. This relatively short half-life is desirable for a hypnotic, as it reduces the likelihood of severe next-day “hangover” effects. However, this half-life is significantly prolonged in the elderly (to around 7-9 hours) and in individuals with severe liver disease, increasing their susceptibility to adverse effects.

Section 3: Guidelines for Administration and Dosage

3.1 Recommended Dosage for Adults

The standard recommended dose of Zopiclone for adults (aged 18-65) is 7.5mg, taken orally as a single dose immediately before retiring to bed.6 It is crucial that the medication is taken only when a full night’s sleep (at least 7 to 8 hours) is possible. Taking the tablet and then attempting to stay awake, or waking before a full sleep period has elapsed, significantly increases the risk of next-day cognitive and psychomotor impairment, including memory loss and dizziness.

The principle of using the lowest effective dose for the shortest possible duration should always be followed. Taking a dose higher than 7.5mg, or taking a second dose during the same night, is dangerous and can lead to overdose.

3.2 Critical Adjustments for Special Populations

Certain populations are more vulnerable to the effects of Zopiclone due to physiological changes that alter how the drug is processed. For these groups, dose adjustments are a critical safety measure.

• Elderly (Over 65 years): For individuals over the age of 65, a lower starting dose of 3.75mg is recommended. This is because older adults typically have a slower metabolism and clearance of the drug, leading to a prolonged elimination half-life and higher plasma concentrations. This increased sensitivity heightens the risk of adverse effects such as excessive sedation, confusion, impaired balance, falls, and hip fractures, which can have devastating consequences in this age group.
• Hepatic and Renal Impairment: Patients with impaired liver or kidney function should also begin treatment with a reduced dose of 3.75mg. The liver is the primary site of Zopiclone metabolism, so severe hepatic impairment can drastically reduce its clearance, leading to drug accumulation and toxicity. While renal impairment has a lesser effect on the parent drug, clearance of its metabolites may be affected.

3.3 The Rationale for Short-Term Treatment (Maximum 4 Weeks)

Official clinical guidelines from bodies such as the NHS state with unequivocal clarity that Zopiclone is licensed and intended for short-term use only. The recommended maximum duration of continuous treatment is four weeks, and in many cases, a course of two weeks is sufficient.

This strict time limit is not an arbitrary guideline but the most critical safety control built into the drug’s intended use. There are two primary clinical reasons for this restriction:

1. Development of Tolerance: The body adapts to the presence of Zopiclone relatively quickly. After a few weeks of continuous use, its hypnotic effects begin to diminish as the brain becomes less sensitive to the drug. This phenomenon, known as tolerance, may lead a user to increase their dose in an attempt to achieve the original effect, escalating the risk of adverse events and dependence.
2. Risk of Dependence: The most significant reason for the 4-week limit is to mitigate the high risk of developing physical and psychological dependence. Continuous use beyond this period allows the body to become accustomed to functioning with the drug, leading to a state where its absence triggers a withdrawal syndrome. Unsupervised access that allows for repeat purchasing beyond this 4-week safety barrier directly undermines this fundamental clinical principle and places the user at a high risk of iatrogenic (medically induced) dependence.

Section 4: Comprehensive Safety Profile and Risk Mitigation

4.1 A Detailed Review of Potential Side Effects

Like all medications, Zopiclone is associated with a range of potential side effects. While many individuals may not experience them, it is essential to be aware of the possible adverse reactions to ensure safe use.

• Very Common and Common Side Effects: The most frequently reported side effect is dysgeusia, a bitter or metallic taste in the mouth, which can be unpleasant but is generally harmless. Dry mouth and next-day drowsiness or sleepiness are also very common.
• Other Potential Side Effects: A wide range of other adverse effects have been reported, including dizziness, headache, confusion, fatigue, nausea, and nightmares. Psychiatric effects such as agitation, irritability, aggression, and even hallucinations can occur, sometimes paradoxically. Amnesia (memory loss) for events occurring after the drug is taken is also a known risk.
• Serious Side Effects: Although rare, serious adverse reactions require immediate medical attention. These include signs of a severe allergic reaction (angioedema), such as swelling of the face, lips, tongue, or throat; difficulty breathing or swallowing; and a severe skin rash (urticaria). Any signs of severe psychiatric reactions, such as delusions or extreme behavioural changes, should also prompt immediate cessation and medical consultation.

The following table provides a structured overview of potential side effects.

Table 1: Zopiclone Side Effects Categorised by Frequency and System

System Organ Class	Frequency	Specific Side Effect	Clinical Notes/Action to Take
Nervous System	Common	Drowsiness, Dizziness, Headache	Do not drive or operate machinery if affected. These effects may persist into the next day.
	Uncommon	Amnesia, Impaired Concentration	Risk is higher with larger doses or if a full night’s sleep is not achieved.
	Rare	Seizures	Occurs primarily in the context of severe withdrawal. Seek immediate medical help.
Psychiatric	Uncommon	Agitation, Nightmares, Irritability	If these occur, the medication may not be suitable. Consult a healthcare professional.
	Rare	Hallucinations, Delusions, Aggression, Confusion	These are serious paradoxical reactions. Stop taking the medication and seek medical advice immediately.
	Not Known	Dependence, Withdrawal Syndrome	Risk increases significantly with use beyond 4 weeks. Do not stop abruptly.
Gastrointestinal	Common	Bitter/Metallic Taste (Dysgeusia), Dry Mouth	Staying hydrated may help. Maintain good oral hygiene.
	Uncommon	Nausea, Vomiting	Take with a small glass of water. Do not take with a heavy meal.
General	Uncommon	Fatigue, Asthenia (Weakness)	Rest is important. Avoid strenuous activities if feeling weak or tired.
Immune System	Rare	Angioedema, Anaphylactic reaction	This is a medical emergency. Seek immediate help (Call 999 in the UK).
Musculoskeletal	Not Known	Impaired balance, Floppy muscles	Increases risk of falls, especially in the elderly.

4.2 Managing Next-Day Impairment: A Warning on Driving and Skilled Tasks

A significant safety concern with Zopiclone is the potential for residual sedative effects that persist into the following day. This “hangover effect” can manifest as drowsiness, dizziness, blurred vision, and impaired cognitive and psychomotor function. These effects create a serious public safety risk.

An individual’s ability to perform skilled tasks, particularly driving or operating heavy machinery, can be dangerously compromised. The risk of a road traffic accident is substantially increased. Therefore, it is an absolute requirement that users do not drive, ride a bicycle, or operate any potentially dangerous machinery until they are certain that they are no longer affected.16 This period can be longer than 12 hours after taking the dose, especially for the elderly or those on higher doses.

This risk of impairment is directly linked to an increased incidence of falls and subsequent hip fractures, a major cause of morbidity and mortality in the elderly population. The decision to take Zopiclone therefore carries a responsibility not only for one’s own safety but also for the safety of others.

4.3 Parasomnias and Complex Sleep Behaviours: A Significant Risk Factor

One of the most concerning and unusual risks associated with Zopiclone is the occurrence of parasomnias, specifically complex sleep behaviours. There are numerous reports of individuals performing activities while not fully awake, with no subsequent memory of the event.

These behaviours can include:

• Sleepwalking
• Sleep-driving
• Preparing and eating food
• Making phone calls
• Engaging in sexual activity

These actions are not only bizarre but can be extremely dangerous, both for the individual and for others (e.g., sleep-driving). This risk is present even from the very first dose and is significantly exacerbated by the concurrent use of alcohol or other CNS depressant medications. If a user experiences any such complex sleep behaviour, it is imperative that they discontinue treatment with Zopiclone immediately and consult a healthcare professional.

Section 5: The High Risk of Dependence, Withdrawal, and Addiction

5.1 The Pathophysiology of Zopiclone Tolerance and Physical Dependence

The human brain strives to maintain a state of equilibrium (homeostasis). When Zopiclone is taken regularly, its constant enhancement of GABAergic inhibition prompts the brain to adapt. It may reduce the number of GABA receptors or decrease its natural production of GABA. This adaptation is the basis of tolerance, where a progressively higher dose of the drug is needed to achieve the original hypnotic effect.

If use continues, particularly beyond the recommended 4-week period, this adaptation can progress to physical dependence. This is a physiological state where the brain and body have re-calibrated to function “normally” only in the presence of the drug. At this point, the absence of the drug will trigger a withdrawal syndrome as the system becomes hyper-excitable without the drug’s inhibitory influence. It is crucial to understand that physical dependence can develop even when the drug is taken at the prescribed dose, if it is taken for a prolonged period. Factors that increase the risk of developing dependence include long-term use, high doses, a personal or family history of substance abuse, and, critically, use without medical supervision.

5.2 Recognising the Symptoms of Zopiclone Withdrawal Syndrome

The abrupt cessation or rapid reduction of Zopiclone in a dependent individual can precipitate a withdrawal syndrome. The symptoms are often the opposite of the drug’s effects and can range from uncomfortable to life-threatening.

Common withdrawal symptoms include:

• Rebound Insomnia: A return of sleeping problems, often worse than the original condition.
• Anxiety and Agitation: Feelings of intense worry, restlessness, and panic attacks.
• Physical Symptoms: Tremors, muscle aches and cramps, sweating, and heart palpitations.
• Gastrointestinal Disturbances: Nausea and stomach cramps.
• Sensory Disturbances: Hypersensitivity to light, noise, and physical touch.

In more severe cases, often associated with long-term, high-dose use, the withdrawal syndrome can mirror that of benzodiazepines and may include:

• Psychiatric Symptoms: Confusion, hallucinations, delirium, and paranoia.
• Neurological Symptoms: Derealisation (feeling that one’s surroundings are not real), depersonalisation (feeling detached from oneself), and numbness or tingling in the extremities.
• Seizures: In very rare and extreme cases, grand mal seizures can occur, which are a medical emergency.

One published case report detailed a 43-year-old male who had taken Zopiclone for 12 years at doses up to 112.5mg daily. Upon attempting to stop, he experienced severe withdrawal symptoms including palpitations, sweating, irritability, hallucinations, and impulsive behaviour, requiring psychiatric hospitalisation. This case powerfully illustrates the profound severity of withdrawal from long-term, high-dose unsupervised use.

5.3 The Clinical Imperative for Gradual Dose Tapering

Given the severity of the potential withdrawal syndrome, it is a clinical imperative that Zopiclone is never stopped abruptly following a period of prolonged use (more than 4 weeks). The only safe method for discontinuation in a dependent individual is a slow and gradual dose reduction, known as tapering.

Tapering allows the brain to gradually re-adapt to functioning without the drug, which minimizes the intensity of withdrawal symptoms. This process should be highly individualised and ideally conducted under the supervision of a healthcare professional who can adjust the rate of reduction based on the patient’s response. The process can take many weeks or even months to complete safely.

Table 2: Illustrative Zopiclone Tapering Schedule for Harm Reduction

Disclaimer: The following schedule is an illustrative example based on NHS guidance and is intended for harm reduction information only. It is not a substitute for professional medical advice. Any attempt to withdraw from Zopiclone after long-term use should be discussed with and supervised by a qualified healthcare professional. The rate of reduction must be individualised.

Stage	Starting Daily Dose	Tapered Dose (at night)	Duration at this Dose	Clinical Notes
Initial	15mg (Off-licence dose)	11.25mg	1-2 weeks (or longer)	This is the first reduction step. Monitor for withdrawal symptoms like anxiety or insomnia.
Change 1	11.25mg	7.5mg	1-2 weeks (or longer)	Reduce to the standard therapeutic dose. The patient may need time to stabilise here.
Change 2	7.5mg	3.75mg	1-2 weeks (or longer)	Reduce to the lowest available tablet strength. This can be a difficult step.
Change 3	3.75mg	3.75mg on alternate nights	1-2 weeks (or longer)	This step helps the body adjust to nights without the medication.
Change 4	3.75mg on alternate nights	Stop	–	After successfully managing alternate nights, the medication can be stopped completely.

Section 6: Clinically Significant Drug and Substance Interactions

6.1 The Potentially Fatal Combination with Alcohol and Other CNS Depressants

The most critical and dangerous interaction is between Zopiclone and other central nervous system (CNS) depressants, especially alcohol. Both substances suppress brain activity. When taken together, their effects are not just additive but synergistic, meaning the combined effect is far greater than the sum of the individual effects.

This combination can lead to profound sedation, loss of consciousness, severe respiratory depression (shallow or stopped breathing), coma, and potentially death. For this reason, alcohol must be strictly avoided while taking Zopiclone.

Similar severe risks apply when combining Zopiclone with other CNS depressants, including:

• Opioid pain medications (e.g., codeine, morphine, tramadol) and illicit opioids (e.g., heroin).
• Benzodiazepines and other sedatives.
• Certain antidepressants (e.g., tricyclics).
• Antihistamines that cause drowsiness.
• Antipsychotic medications.
• Recreational drugs such as cannabis.

6.2 Key Interactions with Prescription and Over-the-Counter Medications

As Zopiclone is primarily metabolised by the CYP3A4 liver enzyme, any substance that affects this enzyme’s activity can alter the concentration of Zopiclone in the blood, leading to either toxicity or treatment failure.

• CYP3A4 Inhibitors: These substances slow down the metabolism of Zopiclone, causing its levels to rise in the bloodstream. This increases the sedative effect and the risk of side effects. Common inhibitors include:

• Certain antibiotics (e.g., erythromycin, clarithromycin).
• Antifungal medications (e.g., itraconazole, ketoconazole).
• Certain antiviral medications used for HIV (e.g., ritonavir).
• Grapefruit and grapefruit juice.

• CYP3A4 Inducers: These substances speed up the metabolism of Zopiclone, causing its levels to fall. This can reduce or eliminate its hypnotic effect, leading to treatment failure. Common inducers include:

• Certain anti-seizure medications (e.g., carbamazepine, phenytoin).
• The herbal supplement St. John’s Wort.
• The antibiotic rifampicin.

Furthermore, stimulants such as caffeine have the opposite effect of Zopiclone and can counteract its sleep-inducing properties. Caffeinated beverages like coffee, tea, and cola should be avoided in the hours before bedtime.

Table 3: Major Zopiclone Drug Interactions and Clinical Recommendations

Interacting Drug/Substance Class	Specific Examples	Nature of Interaction	Clinical Recommendation
CNS Depressants	Alcohol, Opioids, Benzodiazepines	Synergistic increase in sedation and respiratory depression.	AVOID COMBINATION. This is a potentially fatal interaction.
CYP3A4 Inhibitors	Erythromycin, Ketoconazole, Grapefruit Juice	Increased Zopiclone levels, leading to excessive sedation and side effects.	AVOID COMBINATION. If unavoidable, a dose reduction of Zopiclone under medical supervision is required.
CYP3A4 Inducers	Carbamazepine, St. John’s Wort, Rifampicin	Decreased Zopiclone levels, leading to loss of hypnotic effect.	AVOID COMBINATION. The therapeutic effect of Zopiclone will be significantly reduced or absent.
Stimulants	Caffeine	Antagonistic effect, counteracting the sedative properties of Zopiclone.	Avoid consumption of caffeine for several hours before taking Zopiclone.

Section 7: Absolute Contraindications and Overdose Protocol

7.1 Populations Who Must Avoid Zopiclone

There are specific medical conditions and circumstances in which Zopiclone use is considered unsafe and is therefore contraindicated. Individuals with any of the following conditions must not take Zopiclone:

• Known hypersensitivity or allergy to Zopiclone or any of its excipients.
• Myasthenia gravis, a neuromuscular condition causing severe muscle weakness.
• Severe respiratory failure or insufficiency, as Zopiclone can suppress the drive to breathe.
• Severe sleep apnoea syndrome, a condition where breathing repeatedly stops and starts during sleep.
• Severe hepatic impairment (liver failure), as the liver is unable to metabolise the drug effectively, leading to toxic accumulation.

Extreme caution is also warranted, and use should generally be avoided, in individuals with a personal history of alcohol or drug abuse, or certain personality disorders, due to the heightened risk of dependence and misuse.

7.2 Guidance Regarding Pregnancy and Breastfeeding

Zopiclone is generally contraindicated for use during pregnancy and breastfeeding. Use during late pregnancy may lead to adverse effects in the newborn, including hypotonia (floppy muscles) and respiratory depression. The drug is known to be excreted into breast milk, and its effects on a nursing infant are not well established.

7.3 Recognising the Signs of Overdose and Emergency Response Actions

Taking more than the recommended dose of Zopiclone can be dangerous and constitutes a medical emergency. It is vital to recognise the signs of an overdose in oneself or others.

Symptoms of a Zopiclone overdose include:

• Feeling extremely drowsy or confused.
• Falling into a very deep sleep, potentially progressing to a coma.
• Hypotonia (floppy muscles) and loss of coordination.
• Feeling dizzy, light-headed, or faint due to low blood pressure.
• Loss of balance and falling over.
• Shallow, slow, or difficult breathing (respiratory depression).

Emergency Protocol for Suspected Overdose in the UK:

In the event of a suspected overdose, it is critical to act quickly and follow a clear protocol. The moments of crisis require unambiguous instructions, not nuanced advice.

1. Seek Immediate Medical Advice: If you suspect someone has taken an overdose, or if you have taken more than your prescribed dose, call NHS 111 immediately for advice. Do this even if the person seems fine or you do not feel any different. The effects can be delayed.
2. Call for an Ambulance in an Emergency: If the person is unconscious, has collapsed, is having difficulty breathing, is having a seizure, or you are otherwise concerned that it is a serious medical emergency, call 999 for an ambulance without delay.
3. Do Not Drive: Do not attempt to drive yourself or the affected person to the hospital. Your coordination and judgment may be impaired. Wait for the ambulance to arrive.

Section 8: Support Resources and Responsible Use

8.1 Non-Pharmacological Strategies for Managing Insomnia

Pharmacological treatment with medications like Zopiclone should be viewed as a short-term, last-resort measure. A responsible and sustainable approach to managing insomnia focuses on non-drug strategies that address the root causes of poor sleep. Adopting good sleep practices can often resolve insomnia without the need for medication.

• Sleep Hygiene: This refers to a set of habits and environmental factors that are conducive to good sleep. Key principles include:

• Consistent Schedule: Go to bed and wake up at the same time every day, including on weekends.
• Create a Restful Environment: Ensure your bedroom is dark, quiet, cool, and comfortable. Use blackout curtains, earplugs, or an eye mask if necessary.
• Avoid Stimulants: Avoid caffeine, nicotine, and alcohol for several hours before bedtime.
• Wind-Down Routine: Establish a relaxing pre-sleep routine, such as taking a warm bath, reading a book (not on a screen), or listening to calming music.
• Limit Screen Time: The blue light emitted by phones, tablets, and computers can interfere with the production of the sleep hormone melatonin. Avoid screens for at least an hour before bed.
• Cognitive Behavioural Therapy for Insomnia (CBT-I): This is a highly effective, evidence-based psychological therapy that is now considered the first-line treatment for chronic insomnia. It helps patients identify and change the negative thoughts and behaviours that are perpetuating their sleep problems.
• Lifestyle Factors: Regular daytime physical exercise can promote better sleep, but avoid vigorous exercise within a few hours of bedtime. Getting exposure to natural daylight, especially in the morning, helps to regulate the body’s internal clock.

8.2 UK Helplines and Services for Prescription Drug Dependence
