I have finally after 4 years of Cymbalta, decided that it was not necessary to continue its use. Did it slowly and monitored my side effects so that they were manageable. However, WEIGHT GAIN is one I cannot manage at ALL! Been same weight for 12 years prior to these last 6 weeks. I have managed to put on 2 pounds every week? Doing and eating absolutely nothing different. Is this going to stop or do I go back on it? Yes I have been exercising and eating healthy that is what I have always done. I am scared! When or if ... does it end???
