Lamictal is weight netrual for me. I had to get off all the meds that caused weight gain. I just couldn't deal with it emotionally anymore. I lost almost 60 pounds since and I'm continuing to lose more. The only issue with lamictal is the horrifying nightmares and night terrors. Its messing up my teeth too. I would rather have that then the weight gain though. I don't have a lot of luck with psych meds. I'm better off them then on them.
