The day has ended. Your nervous system has not.

No wearable. No pill. Tell it when you sleep and what is still on. It writes the three changes for this week from published sleep guidance.

23:40
With a 23:40 bedtime, leave caffeine after 15:40. If you wake at 07:10, see outdoor light between 07:10 and 08:10. Charge the phone where you cannot reach it from the pillow.
A day that still looks fine
The day has ended. Your nervous system has not.
Not laziness. Last night did not give you back.
No diagnosis. A body borrowing tomorrow.
What it actually does
Bedtime, wake time, the afternoon drop, the phone, caffeine, and the one thing you want back.
Caffeine's half-life is about five hours. A large dose six hours before bed can still shorten sleep. Adults are commonly advised to get at least seven hours. Morning outdoor light anchors the clock.
Dimmer light, a longer exhale, and a phone that spends the night out of reach.
Seven nights, three moves
One warm lamp. The phone leaves the bed. Four longer exhales, then stop while it is still easy.
The same bedtime. A slightly cooler room. Ten minutes to close the day, even when you are already tired.
Outdoor light in the first hour. Caffeine stops earlier. Write down one thing that actually felt lighter.
The same bed
