I have been on wellbutrin 75mg twice a day for about 2 weeks, the only thing I dont like is the shocks I feel little shocks sometimes for about 20 minutes after i take it, i was taking lexapro for about a year and it helped for my depression butthe side effects were horrible no sex drive and I gained about 20 pounds, so 3 weeks ago my dr switched me from lexapro to wellbutrin so hopefully this works with out all the bad side effects, my dr said wellbutrin shouldnt put weight on me....hope not
