I just was diagnosed a month ago with FM. After every test in the book it is said that I have FM. Chronic muscle aches and fatigue are my biggest problems. I have really tried to keep up my exercise. I play tennis 3-4 days a week. I have noticed that taking flexeril at night and 1/2 ambien has helped along with rest. After a big weekend and being on my feet too long I am really bad today. I have full blown body aches. i feel like I just climbed Mt Everest with no rest. I do take prozac and I have for years. I am curious about elivil. Does anyone have any experience with medications that have worked for them. Any side effects?
