This is generally a good practice regardless of sleep disorders. I fall asleep as soon as my head hits the pillow because i go to bed to sleep. I dont go to bed to scroll on my phone. I dont have a tv in my room. I will be on a couch or a chair until im done with phone/tv/games, then... instant sleep, and staying asleep all night.

My wife is amazed by my ability to sleep, but she reads on her kindle and doom scrolls in bed for hours some nights
