The first time I stopped taking it it was the name brand and I had zero symptoms. I was in the best days of my life and everything was roses for a couple decades! No withdrawal. I actually felt clearer and happy. Two decades later and I've had severe relapse of PTSD (which sucks, I hate it) so I tried wellbutrim again to help. I have no idea if was helping or not but I think not since I went into melt down/SI recently. So I just quit taking it since I was in hyper vigilance, terror, guilt cycles that the med. was obviously not helping me. So far I have no idea if I am having withdrawal. I don't think I am-- Sorry this is no help is it?
