A few years back a lost a lot of weight on Topamax and serzone. Unfortunately, I needed to change meds and have gained most of it back. Never could take lithium. Am now taking Emsam, Lamictal which is supposed to be weight neutral, I am not finding it so, Topamax 200 mg, Chantrix because I relapsed smoking in December, my last crash, and klonapin. I am hoping to have good results with the topamax again. I also go to the gym every day, but still continue to gain weight. I watch what I eat, and stay under 2000 calories a day, that is good for me as my height is 5'7. I am hoping to talk my pdoc out of the Lamictal as it makes me so tired.
