From a professional standpoint, I believe Wellbutrin to
be a great medication and have worked with many clients who have found it to
be incredibly helpful. I have yet to hear of any "failures" with regard to Wellbutrin. In general, Wellbutrin takes about 4 weeks to start working. Side effects of Wellbutrin SR include agitation, constipation, dizziness, dry mouth, insomnia, nausea, rash, sweating, and/or weight loss.
