I have only been on Wellbutin for about a week. I am new to this. My main side effect is that I am tired all the time. I read how it gives many of you energy. Well not me. I am tired all the time and I to have feeling of just not caring. It's like I fell nothing. No emotions at all. My co-workers asked me what was wrong, because I am normally outgoing, the social butterfly of our office. The past week, I have not felt like being around people. Like it takes up too much of my energy to be social. I have also had a severe lack of concentration and some memory loss. I am ADD but it seems like it is making me worse. I also suffer from insomnia, not due to the medication. But I have found that even when I take my medication for sleep, I can't fall asleep. If anyone has experienced loss of emotion, you can email me at ******. I am interested in knowing how you dealt with it.
