what i do is settle down before i sleep. I either read a book or play my guitar. It usually helps.
also, i read that adding variety can help. sleep with your shirt on, with your shirt off, sleep naked, sleep on the couch, in a sleeping bag, in the car.
whatever helps man.
o yeah, and things to avoid if you're having trouble: TV, loud or repetitive music (gets stuck in your head), exercise.
I've also heard that certain foods can help you fall asleep. and apparently turkey has something in is (forget what it's called) that puts you to sleep.
so rock on and sleep hard
