It's a bit cliche but the most accurate book is the one you can write for yourself.

Seriously, make yourself a guinea pig, experiment and have fun. All whilst making note of how things are affecting your sleep.

Here are some starter experiments:

-no tech within 1 hour of bedtime

-do household chores or go for a walk/run a few hours before sleeping

My last tip for all of this is to have self-compassion, a majority of things won't work but that's the methodologies problem not yours. Decide if you want to tweak it or move on.

Good luck and best wishes.
