Cheesesquid, Lamictal is completely weight neutral. I actually lost weight on it. I went from 120 to 113 in a month with no effort at all. It kind of worried me actually because at 5'4" I don't want to be 113, ya know? Anyway, Lamictal will definitely NOT cause weight gain.

I'm pretty sure Lamictal and Lithium can be combined. The NP I was seeing for psychopharm discussed adding Lithium, but I was feeling great and didn't want to mess with what was working.
