The doctors tried me on Cymbalta after the Lyrica failed. Unfortunately, this one I could not take either. Too many side effects interrupting with daily function. Today after seeing a rheumatologist, he tells me that I do not appear to be a FS patient, and that he is baffled by the multitude of symptoms I have. His recommendation is the Mayo Clinic..That may be my next step. Today is a bad day, and regardless whether you have fibro, chronic fatigue or any other immune disorder, it hurts, it's real, and those us who deal with it, are on your side. Just wish some doctors would get on board and help...Kim
