I read on this website that it is best to put on your hi fi, ipod, or whatever you have and go to sleep by the side of your bed or near you (not headphones) for some reason. It works best if you have an ipod because you won't get woken up by the cd or tape rewinding.

Tryed it last night but i couldn't get to sleep with it on but i will try again tonight. I think i will have a greater chance of falling asleep if i put my ipod on when i wake in the middle of the night because i find it alot easier to fall asleep once i have been asleep for a few hours.
