Why can I not sleep?

Not a diagnosis: a head start. These are the three drivers most worth checking first, based on what the evidence says gets missed most often.

01

The 3am wake-up

Often a blood sugar dip triggering cortisol. A protein-heavier dinner is the cheap experiment.

02

Cortisol timing

Stress hormone peaking at night instead of morning flips your rhythm. Screens and late work feed it.

03

Alcohol’s false friend

It knocks you out, then wrecks the second half of the night. Track it honestly.

Worth asking your GP about

HbA1c, thyroid; track caffeine, alcohol and timing in a journal first

Do this, this week

1. Start a two-minute note in the free journal that asks back, so the pattern becomes visible.
2. Take the test list above to your GP; the Health Journal will help you say it clearly.
3. Read the evidence: Melatonin for Sleep: Evidence, Dosing and the UK Rules.
