Imagine a place where you are most cozy and visit it every night when you try to sleep. And then maybe sound machines. And finally, deep breathing. Slowing your heart down through this will physically make your body want to go to sleep (so basically meditiation).

I do all of these in tandem, I have the sound machine going and I settle into my cozy part of my brain and then imagine my lungs as a cup filling up with water to the top while inhaling and then draining out as I exhale. The trick with this is to not stress yourself thinking about if you’re doing your breathing right, just try and relax and focus.

Also melatonin. But that isn’t effective for every situation.

Good luck.
