just purchased a book titled "What Your Doctor May Not Tell You About Fibromyalgia Fatigue", and in it the author (Dr. R. Paul St. Amand, M.D.) mentions a protocol that he himself uses, and that he also tells all of his fibro patients to try. It requires you to take upto, but not limited to 2400mg of guaifenesin (Mucinex) daily. He says that with this protocol, you will notice that your symptoms will at first become worse, but will gradually disappear.
