HI,
I'd like to post that I also have fibromyalgia, and have recently read a superb book called From Fatigued to Fantastic, which explains about breakthrough in treatments. The doctor who wrote it had it. There are some brilliant suggestions in there such as CORvalen, and other supplements that I'd never heard of and I've started using and now I'm much more energetic..... after 22 years of having it!!!!
I do belly dance by the way as the best and most fun way and gentle way of keeping fit for the last 15 years.
