Hey crystalrose, I've only just started sleeping properly again, 2 things that have helped me the most have been yoga, when I can't sleep I get up and do yoga. It doesn't always put me back to sleep but the next day I don't feel so bad. The other thing has been herbal teas, and I have tried heaps of alternative/eastern medicine which never helped me. And loads of herbal sleeping pills etc...

I have no idea why these work but Sleepytime tea and Tension Tamer from Celestial Seasonings are amazing for me. Once again not a 100% cure but helpful.

Zilchhour's suggestion works for me (sometimes) too.
