I know there has been a lot of discussion on cymbalta, but I couldnt find anywhere if anyone gained weight with it. My doctor just switched me yesterday from Nortriptyline to Cymbalta because I have gone up like 2 clothes sizes and my pain was not any better. I have never had a weight problem in my entire life and so I know its the nortryptyline, but wondering if Cymbalta will continue to weight gain. Also, I took it at night before going to bed and did not feel sick, but I feel very sleepy and spacey today. I am also on Clonopin for sleep, Ultracet for Pain, and Atenolol for MVP.
