I was on Paxil for almost fifteen years but switched to Wellbutrin SR 150 mg 1x daily two weeks ago. I have experienced every side effect in the book so far--nausea, dizziness, and severe muscle pain. I have not noticed any benefits yet to this medication. My mood is flat other than wanting to burst into tears, and I am ANGRY. When will (and do?) the side effects fade? When does the Wellbutrin start to boost mood? I have had a return of sexual function, for which I am grateful. However, I would like to have a REAL life and a sex life.
