Doodle Jump, I have a fan that has a button that rattles around in it’s little button place while the fan is on. Sure, it’s a certain steady noise in the room – but it usually keeps me up! I would get up in the middle of the night trying to tape that thing so it just wouldn’t move! I really like going to sleep to the sound of rain…
Try listening to music, drinking warm milk, reading a book you don’t find interesting…sometimes concentrating on the fact that one can’t fall asleep is what keeps one awake.
