My psych also added cymbalta to my Wellbutrin. I wasn’t noticing much of an improvement either, and then I ran out and had to wait a couple of weeks to get it filled again. I had a few withdrawal type symptoms, but after a few days, and all the Cymbalta was out of my system that was when I realized just how much it was helping. I’m not saying that it’s fabulous, and I certainly wouldn’t take it alone for the kind of depression I have, but I do know that it absolutely is value added for my medication regime. And I will say, I am also using it partially for pain so between the two of them it has really helped me.
