ADHD and sleep: practical steps and when to seek help

“Not sleeping well” can mean several different things: struggling to stop an evening activity, lying awake after going to bed, waking repeatedly, or feeling unrefreshed in the morning. Describing which part is difficult gives a sleep conversation more direction than aiming for a perfect bedtime routine.

Sleep difficulties are common in ADHD. Regular routines and a period of winding down are among the practical supports suggested by Leicestershire Partnership NHS Trust¹. They are starting points, not a guarantee of better sleep or an explanation for every sleep problem.

Key points

Look at the sleep pattern and its daytime effects, not just the number of hours.
Make changes that fit your circumstances and seek help for persistent problems.
Mention breathing difficulties, uncomfortable legs and medicine changes.
Melatonin is prescription-only in the UK; discuss sleep products before using them.

Understanding what is happening

Insomnia involves regularly having difficulty falling asleep, staying asleep or returning to sleep after waking early. It can leave you tired, irritable or unable to concentrate during the day. Stress, anxiety, noise, caffeine, alcohol, shift work and some medicines are possible contributors.²

Most healthy adults need around seven to nine hours, but individual needs vary. How you feel during the day also matters. Persistent sleep problems can affect mood, relationships and everyday tasks. A single target number therefore cannot describe the whole problem.³

Questions to reflect on: think about where the difficulty begins. Is there little time available for sleep, or are you awake despite having the opportunity? Does the pattern change on days off? What interrupts the evening? You do not need to solve these questions before seeking help; they are ways to describe your circumstances.

Build a routine you can actually use

NHS advice includes getting up at a consistent time, going to bed when sleepy, allowing time to relax, and making the bedroom dark and quiet. It advises avoiding tea, coffee, alcohol and smoking for at least six hours before bed. Do not drive when sleepy.²

You could try: choose one obstacle and one change, rather than redesigning the whole evening. For example, if preparing for tomorrow keeps expanding into bedtime, choose a short earlier slot to put essential items together. Decide what “finished enough” looks like before starting. If a reminder disappears among other notifications, give it a specific label such as “save work and begin getting ready”.

A routine can be written as a short sequence in your own words. It need not include a special app, purchase or elaborate relaxation activity. If reading is appealing, put the book where you plan to use it. If the environment is the main problem, identify the change you can realistically make and the issue you need help with.

Shift work, caring responsibilities or shared accommodation may make conventional advice difficult to follow. A question to ask: “These are the hours I can realistically protect for sleep; how can we adapt the plan?” This invites a discussion of your actual circumstances rather than setting a standard you cannot meet.

Make a brief sleep note

Preparing for an appointment: a simple record can help organise what you want to say. It is not a validated sleep assessment, and it does not need exact measurements. Consider noting:

Roughly when you went to bed, fell asleep and got up.
Whether you woke during the night and what you noticed.
Daytime sleepiness and which activities became difficult.
The timing of medicines, caffeine and alcohol.
Any unusual circumstances, such as a shift change or illness.

You could use a few representative nights rather than creating another demanding daily task. Estimates are fine. Leave gaps if you cannot remember, and bring the note as it is. The aim is to support a conversation, not to produce a score or prove that the problem is serious enough.

Look beyond ADHD when symptoms suggest something else

Tell your GP about breathing pauses, gasping or choking during sleep, loud snoring or marked daytime tiredness. These can be symptoms of sleep apnoea. A GP may arrange assessment at a sleep clinic, sometimes using overnight monitoring at home. If someone has noticed the symptoms, their observations can be useful.⁴

A strong urge to move your legs, with uncomfortable sensations that are worse when resting at night, can suggest restless legs syndrome. See a GP if it is interfering with sleep or mental health, or self-care has not helped. Similar symptoms can have other causes, so the description alone does not establish a diagnosis.⁵

These are examples of problems worth describing separately. They are not a list of conditions that everyone with ADHD should expect to have.

Medicines and professional help

If sleep changed after a medicine was started or adjusted, tell your GP, pharmacist or prescriber. The NHS advises checking the medicine leaflet and discussing possible medicine-related sleep problems. Ask for a review of the plan rather than changing a prescribed dose or schedule yourself.³

See your GP when sleep difficulties have continued for months, changes to habits have not helped, or daily life is hard to manage. Treatment may include cognitive behavioural therapy for insomnia, which addresses thoughts and behaviours that keep sleep difficulties going.²

Questions to ask: “What possible causes need checking?”, “Is treatment for insomnia appropriate?” and “When should we review this?” You can also ask for instructions in a format you can refer back to, especially if you are tired during the appointment.

What about melatonin and other sleep products?

Melatonin is a prescription-only medicine in the UK. It is mainly used for short-term sleep problems in people aged 55 and over, although specialists sometimes prescribe it for other sleep difficulties in adults and children. That does not establish that it is suitable for every adult with ADHD.⁶

The NHS advises against ordering melatonin supplements online. Discuss products with a pharmacist or prescriber, including anything already being taken.⁷ You could try: bring the packaging or a photograph of the ingredient list, so the conversation concerns the actual product rather than just the words “sleep supplement”.

Frequently asked questions

Is poor sleep automatically part of ADHD?

No. Sleep can be affected by health, circumstances, surroundings and medicines. Explain the pattern so possible causes can be considered.³

Should I keep trying routines if I am exhausted?

You can seek help when the problem is affecting daily life or changes have not helped. You do not need to perfect a routine first.²

Is snoring worth mentioning?

Yes, especially alongside breathing pauses, choking or substantial daytime tiredness. Those features need assessment for possible sleep apnoea.⁴

Do I need a wearable device for an appointment?

You could try: begin with your own description and an approximate note if useful. Ask the clinician whether any further monitoring is needed rather than assuming you must buy equipment before asking for help.

Can I buy melatonin because it is sold abroad?

Availability elsewhere does not change its UK prescription status. The NHS advises against online melatonin supplements; ask a clinician about suitable options.⁷

Limits of this advice

General sleep guidance cannot identify why one person is struggling or predict which change will help. The practical examples are suggestions to adapt to your circumstances. Persistent symptoms, safety concerns and possible sleep disorders deserve individual assessment.
