I've been taking Wellbutrin for about three years now, and never noticed anything that I thought was a side-effect (my original dose made me sweat and shake like crazy, so it was cut in half). Anytime I exercise at a reasonable, moderate pace, my face gets as red as a tomato, and my temperature goes up around 103-104 degrees (F), even if I'm not exerted. My mom mentioned that the same thing used to happen to her when she took Wellbutrin. Is this a side-effect? I always thought I was just really out of shape, but seeing as I exercise several times per week and this happens even when my breathing is normal and relaxed...??
