I also deal a couple months at a time with insomnia and restless leg syndrome. I would do some light exercise and stretching that would ease it off and most time I could get to sleep. It's lightened up considerably in the last year while I've been getting my fillings replaced, but some good stretching really helps. Sometimes I even listen to some mind soothing CD's like yoga type ones or rain effects that help.

Good luck with that and know that the future is brighter!
