I took Wellbutrin for a while but didn't like it at all. It was activating but didn't give me energy if that makes any sense. It was like I could only feel the after effects of being overstimulated. I was exhausted all the time but couldn't sleep, I just felt like the life had been sucked out of me. I felt agitated on it too. I've taken stimulant meds like Adderrall and Ritalin and neither had such harsh effects on me. But everyone's different and have the opposite experience so it depends on your body and how it responds to certain chemicals. Buspar did not have any effect on me - no weight gain though so that is a positive.
