The number, drawn
Why it matters
Caffeine can get in the way of sleep, and general NHS guidance says to keep it away from bedtime. The NHS page on adult ADHD also suggests avoiding caffeine close to bedtime. Adults with ADHD already report more sleep problems than peers without ADHD. Knowing when you have caffeine can help a clinician assess your sleep, but caffeine is not an established ADHD treatment.
How to do it
- List your caffeinated drinks and roughly when you have them.
- Note when you try to sleep and how your sleep goes.
- Ask a clinician or pharmacist how your caffeine timing fits your sleep and any medicines.
Use this to prepare for a conversation, especially if you take medicines, are pregnant or have ongoing sleep problems.
Putting it into practice
In real life
- Bring a note that your last coffee is late afternoon and you struggle to fall asleep.
- Include tea and energy drinks when describing your caffeine use.
Watch out for
- Common mistakeCounting only coffee misses other sources. Include every caffeinated drink.
- Common mistakeUsing caffeine as ADHD medication skips the assessment. Talk about the problem you're trying to solve.
