If you have trouble sleeping, the trick is to
get out of your head.
Play something like this on your phone as you're in bed. Just loud enough for you to follow the stories. But not loud enough to disturb you once you pass out. You probably won't make it past 2 or 3 stories before you're sleeping like a baby. And having really fucked-up dreams.
