In one line

The last thing I read decides how I sleep.

One night, drawn

A typical night from the ring: deep sleep at the bottom, awake at the top.

The diary

Night 4

Investor email at 00:30. Read it in bed. Did not sleep until 02:10 even though the news was good.

Night 12

New rule: laptop closed at 22:30, phone on the kitchen shelf. Asleep at 23:40. The ring gave me my first 7-hour night of the study.

Night 27

Kept the rule for fourteen nights out of sixteen. The two I broke were both Sundays.
