Oh gosh i know how you feel, i am generally good to drift off to sleep but i wake up about 1am and cannot for the life of me get back to sleep.
ive tried almost EVERYTHING un medicated, the thing i do now is switch on the tv (even tho its those stupid danoz adds) watch that for a bit go get a glass of milk and generally my eyes start drifting off.
i have been to the dr about mine and was diagnosed with stress related innsomia.
