"Hi I was on cymbalta for 6 weeks  gained 17 lbs.  I started back to Effexor. Have lost 4 lbs in a week of coming off cymbalta and going back on Effexor. Cymbalta made me retain fluid. I was miserable on cymbalta.  Rheumatologist wanted me to try cymbalta so I gave it a try for fibromyalgia    I went through a little electric feeling for about 3 days coming off cymbalta. Can anyone tell me what else is good to take for the fibromyalgia pain. Effexor seems to help some , but still having some pain."
