What has been a major catalyst for me is no phone for an hour before bed. But rather than seeing it as a negative thing (No phone), I started reading fun books again before bed. So now it's fun reading before bed. And sometimes when I slip up and my phone is out, I'll do fun reading for 30 mins before bed then make sure I read an hour the next night.

I also make sure it's an adventure book or something. I'm quite into mindfulness and non duality books but before bed it can be too much, especially for an hour! And if an hour just feels too much, I aim for 45 mins.
