For me Wellbutrin is stimulating. There were times when I was stimulated and felt bad also, this was not a good combo. I like Wellbutrin, I'm a big fan, but I must use if cautiously and I recommend others with bipolar to always be on the lookout. Wellbutrin is mostly helpful to me in providing energy, reducing my need for sleep, allowing me to have energy enough to chat with people....it's like it makes me hypomanic. It also increases anxiety and heart palpitations too at time. All of these meds have a downside it seems. Can't escape that I guess. I hope you figuring out a solution to your dilemma.
