I'm on Lamictal and have had trouble losing weight . I'm not sure if they are linked . I really really wish I could go back on topomax! I was like 20 lbs thinner when I was on that, and my moods were better . But, it interferes with my birth control .
I had to reduce my lamictal a few months ago and for me it was rough. I recommend tapering off really slowly if you're going to get off it.
