Sleep Reset

Three items on three different clocks, aimed at the three things that break a night: the rhythm deciding when you get sleepy, the moment of falling asleep, and the anxious loop that keeps you up.

The rhythm item works over weeks, which is why the course is four of them rather than one. The falling-asleep item works within the hour and is taken close to bed. The calming item runs in the evening, where rumination does its damage. Stack them on the same clock and they blur into each other; on separate clocks each one has a job you can check. If the anxious loop is the whole problem, run the calming item alone first and see how far that gets you.
