ibromyalgia
"Couldn't believe it could be true but it was. Newly diagnosed with fibromyalgia. I read about Mucinex for fibromyalgia; read that it is a muscle relaxant and enhances the analgesic effect of aspirin and Tylenol; and is enhanced by magnesium.  Went out and bought the 800 mg with 2 aspirin and some magnesium citrate, and it worked!  The pain just seems to dissolve away.  I continue to take 800mg (2, 400mg immediate release tablets) with aspirin and magnesium, three times a day, or 1200 mg twice a day. "
