I have been on Prestiq 50 mg for a few years after being switched from Paxil for depression and generalized anxiety. After a major panic attack last week, and a resurgence of depression that slowly reared its head over a number of weeks, my Dr put me on Welbutrin as well. It has been about 8 days and I feel so anxious, like I need to run, and my mind is racing. Is this a side effect that will eventually go away? It is not constant, but often enough to have me worried. How long can I expect to feel this way? Will I need to take another short term med to get through the this, or will I need to go off the Welbutrin? I am seeing my doctor in a couple of days, so I will ask him, but I thought I might get a quicker answer if I asked here as well. Thank you.
