I've been on 100 mg of Wellbutrin for a week to great results. I feel happier, more focused, and have been enjoying life in a great way. I do however, feel jittery and a little "speedy". I feel like I have taken a 20mg adderall or something similar. I've read online that this is common, and eventually subsides. Does anyone have experience with this? And if so, when did the jitters start to subside? I'm on such a small dose I'm surprised the effects have been this high.
