I don't take as many meds as most people, though I do feel as though I've tried about everything. I take 300mg of Welbutrin XL, 600mg of Trileptal, and 100mg of Trazodone. I was taking something a very high dosage of zeprexa and Trileptal and I thought I didn't need it anymore. I stopped taking it without my doctors consent and ended up in the hospital plus got kicked out of school because I was a liability. The funny thing is, when I was in the hospital they had me on seven meds; five more than I was on originally. I think if you want to stop that med or think it's causing you to gain weight you should ask your doctor first. Maybe they can find something else that would work better for you.
