Sleep problems: what to check before considering medication

You have moved the phone away, tried herbal tea and even gone to bed earlier. Yet night arrives and sleep does not, or it breaks apart at 3 a.m. It is easy to assume that willpower is missing or that the next pill will solve it. But poor sleep is a symptom, not one diagnosis.

There may be too little time available for sleep. Your body clock may be out of step. Stress, hot flushes, pain, sleep apnoea, restless legs, alcohol or a medicine may also be involved. Sometimes a hypnotic makes sense; at other times it covers a clue worth seeing. Before asking “what can I take?”, a more useful question is: “what pattern keeps returning, and what decision would change if I understood it?”

First, name the pattern

Chronic insomnia involves difficulty falling asleep, staying asleep or waking earlier than intended despite having an adequate opportunity to sleep. It also affects daytime functioning and occurs at least three nights a week for three months. That distinction matters: trying to sleep for eight hours and spending much of them awake is not the same as having only five hours available because of work or caring responsibilities.

Pattern	Common clues	Useful first step
Insufficient opportunity	Work, care or leisure cuts the time available	Protect a realistic sleep window
Insomnia	There is time, but sleep or returning to sleep is difficult and the day suffers	Diary, assessment and CBT-I
Misaligned body clock	Sleep is better at times that do not fit daily demands	Review timing, light, shifts and travel
Breathing or movement	Snoring, pauses, gasping or an urge to move the legs	Targeted assessment
Another fragmenting cause	Pain, hot flushes, reflux, mood, substances or medication	Treat sleep and the cause in parallel

Patterns can overlap. Having sleep apnoea does not prevent insomnia, and going through perimenopause does not make every awakening “just hormones”. The goal is not to force yourself into one box. It is to arrive at an appointment with a clearer story.

A 14-day diary, without turning night into an exam

For two weeks, including working days and free days, record:

• bedtime, the approximate time sleep took, awakenings, final waking and rise time;
• naps and how energy, concentration, mood and sleepiness felt during the day;
• caffeine, alcohol, nicotine and other substances, with approximate amount and timing;
• exercise, shifts, travel, pain, hot flushes, late meals and night-time light;
• medicines and supplements, without changing the dose to “test” a theory;
• snoring, gasping, breathing pauses or movements noticed by another person.

Estimate rather than time every minute. Repeated clock-checking can increase arousal. A watch or ring may help you see trends, especially sleep regularity, but it cannot diagnose the cause or measure stages with laboratory precision.

Five groups of causes worth checking

1. Timing, light and the body clock

Shift work, jet lag, very different weekends and too little daytime light can move circadian timing. A stable rise time and natural light during the day are often more useful anchors than forcing yourself into bed before sleepiness arrives. This does not mean that discipline fixes everything. When imposed schedules and biology collide, the plan has to be workable.

2. Mental arousal and learned insomnia

Stress, grief, anxiety or an illness may start the problem. Then another mechanism appears: the bed becomes associated with effort, monitoring and fear about tomorrow. The harder you try to control sleep, the more alert the brain seems to become. This is exactly where CBT-I offers more than a list of healthy habits.

3. Breathing and movement

Frequent snoring, observed pauses, gasping, choking, morning headaches or daytime sleepiness suggest an assessment for sleep apnoea. In some women, fatigue or insomnia is more prominent than the stereotype of falling asleep everywhere. Restless legs usually creates an urge to move at rest, worsens later in the day and improves temporarily with movement.

The AASM restless legs guideline recommends checking ferritin and transferrin saturation when symptoms are clinically significant, as well as reviewing alcohol, caffeine, aggravating medicines and untreated sleep apnoea. Do not start iron on your own: indication and safety need confirming first.

4. Body changes and medical conditions

Hot flushes, night sweats and mood changes can fragment sleep during the menopause transition. Pain, reflux, asthma, thyroid problems, urinary symptoms and some neurological conditions also matter. If this sounds familiar, our guide to perimenopause symptoms can help you organise what to observe. Treating sleep does not replace treating the cause, and the reverse is also true.

5. Substances, medicines and supplements

Caffeine may remain active for many hours; alcohol may make sleep start more easily while worsening the second half of the night. Decongestants, stimulants, corticosteroids and some psychiatric treatments can also alter sleep depending on dose and timing. Bring a complete list to the appointment, including over-the-counter products, melatonin and herbal remedies. Do not stop a necessary treatment to run a home experiment.

Which tests help, and which usually wait?

Tool	When it may help	What it does not do
History and diary	First map of pattern, severity and daytime impact	It does not replace assessment when there are warning signs
Targeted blood tests	Iron for restless legs, thyroid or other tests when the history suggests them	It does not justify indiscriminate panels
Actigraphy	Uncertain circadian timing or a need to estimate patterns across several days	It is not routine for every insomnia case
Sleep study	Suspected apnoea, movements, parasomnia or well-assessed persistent symptoms	One night cannot explain every bad night

A test is worthwhile when its result can change a decision. “Check everything” sounds reassuring, but it also finds incidental results and does not guarantee an explanation.

CBT-I: far more than sleep hygiene

Cognitive behavioural therapy for insomnia, or CBT-I, is the recommended first-line treatment for adults with chronic insomnia, including those with other health conditions. It can be delivered in person or through validated digital programmes. It combines education about sleep regulation, stimulus control, adjustment of time in bed, work on worries and relaxation.

Sleep hygiene helps remove interference, but AASM advises against using it as the only treatment for chronic insomnia. The distinction matters: being told to “avoid screens and drink less coffee” is not the same as receiving a structured therapy.

In a meta-analysis of 20 trials with 1,162 adults, face-to-face CBT-I reduced time to fall asleep by about 19 minutes and overnight wakefulness by 26 minutes on average. Sleep efficiency rose by 9.9 percentage points, while total sleep time did not show a large immediate increase. The studies excluded people with several comorbidities, so the figures inform a conversation rather than predict your result.

The goal is not to produce eight identical hours every night. It is often to reduce the struggle around sleep, rebuild a calmer relationship with bed and function better during the day. Adjusting time in bed may temporarily increase sleepiness and is best guided by a professional, particularly if you drive, do safety-critical work, have poorly controlled epilepsy or are vulnerable to mania.

Where does sleep medication fit?

Taking a hypnotic is not a failure. Guidelines include selected options, often for short periods, when CBT-I is insufficient, is not yet available or there is an individual indication. Choice depends on the type of symptom, age, pregnancy, falls risk, sleep apnoea, other medicines, alcohol and the need to drive.

There are also risks: next-day sleepiness, confusion, falls, tolerance, physical dependence and, rarely, complex behaviour while a person is not fully awake. It makes sense to review periodically what benefit the medicine provides, which adverse effects appear and whether the indication still exists.

A cautious plan for the next 14 days

1. Days 1 to 3: define the problem. Is it sleep onset, awakenings, shifted timing or sleepiness? Record the daytime effect.
2. Days 4 to 7: look for patterns. Add substances, exercise, shifts, pain, hot flushes and medication. If you live with someone, ask about snoring, pauses or movements.
3. Days 8 to 14: stabilise safe anchors. Keep a realistic rise time, seek daytime light, move and create a calm transition at night. Do not sharply restrict time in bed or change medication on your own.
4. At the end: choose the next step. If the problem is improving, keep what helps. If it affects the day, has lasted for months, requires frequent medication or suggests apnoea, restless legs, pain or a mood problem, take the diary to primary care or sleep medicine and ask about CBT-I.

When not to wait

• Breathing pauses, choking or sleepiness while driving: do not drive and seek prompt assessment.
• Suicidal thoughts, extreme agitation or several days with very little need for sleep: seek urgent help.
• Falls, confusion, breathing difficulty or unusual behaviour after a hypnotic: contact a clinician immediately and use emergency care if there is danger.
• Seizures, marked tremor or deterioration after reducing benzodiazepines or alcohol: withdrawal may be an emergency.

Frequently asked questions about sleep problems

How do I know whether I have chronic insomnia?

There is difficulty falling asleep, staying asleep or waking too early despite having enough time and suitable conditions for sleep. It also affects the day and recurs at least three nights a week for three months. An assessment should rule out insufficient schedules, substances and other sleep disorders.

What should I record in a sleep diary?

For 14 days, note when you go to bed, roughly how long sleep takes, awakenings, rise time, naps and how you function during the day. Add caffeine, alcohol, exercise, shifts, pain, hot flushes and every medicine, without changing doses on your own.

Is sleep hygiene enough to treat insomnia?

It can remove obstacles, but it is usually insufficient for chronic insomnia. CBT-I adds active strategies for the bed-sleep relationship, time in bed, worries and relaxation. Guidelines recommend it as first-line treatment.

What is CBT-I, and how much can it help?

It is cognitive behavioural therapy designed specifically for insomnia. In a meta-analysis of 20 trials, it reduced time to fall asleep by about 19 minutes and overnight wakefulness by 26 minutes on average, although individual responses vary and the aim is not to manufacture identical nights.

Should I stop taking sleeping pills?

Not without speaking to the prescriber. There may be a valid indication, but also adverse effects, tolerance or physical dependence. Abrupt withdrawal, particularly from benzodiazepines, can be dangerous and requires an individual, supervised plan.

Do I need a sleep study?

Not for every case of insomnia. It may change decisions when there are breathing pauses, snoring with gasping, movements, unusual behaviours during sleep or persistent symptoms despite an appropriate approach. Clinical history and a diary usually come first.

Can a watch or ring tell me why I sleep badly?

No. It may show trends in timing and regularity, but sleep stages, awakenings and other calculations are estimates. It cannot diagnose insomnia, sleep apnoea or restless legs. Use it as a clue, not a verdict on your night.

When should I seek prompt help for a sleep problem?

Seek prompt help for breathing pauses or gasping, sleepiness while driving, suicidal thoughts, extreme agitation, falls or confusion with a hypnotic, or severe symptoms after reducing alcohol or benzodiazepines. If driving is not safe, do not drive.

This article is educational. Do not start, combine or stop sleep medication or supplements without reviewing your situation with a qualified clinician. If there is sleepiness while driving, breathing difficulty, withdrawal or a mental-health crisis, prioritise safety and urgent care.

Sleep should not become another exam to pass. A good plan starts by understanding the pattern, choosing the least complex intervention likely to help and reviewing how daytime life changes.
