Does Lamictal cause weight gain?

Hi!
Just came across your posting.
I was placed on Lamictal 2+ years ago. I am on 250 mg./day. I gained about 15 lbs the first year, then I lost about 3-4 lbs the second year, and seem to be evening out--my weight varies a couple pounds, but not much.
I was told that Lamictal has no risk of weight gain, and there is much scientific literature that says that there is no 'significant' weight gain vs. placebo, but I have not found it to be so. I have increased my exercise level the last year, and I think that doing so has allowed my body to even out and stabilize, but I think there is something going on either metabolically or in terms of cravings and one's ability to control cravings that has been a side effect. I definitely eat more than I did before.
However, the benefits, for me, have been like night and day than before. I have tried a couple other drugs (wellbutrin, prozac, zoloft) that either made me so tired that I felt like a zombie or made me agitated and changed my personality. On Lamictal, I have had none of these problems. I am freed of the debilitating depressive moods and don't get so high with the mania, but still feel a healthy range of emotions. It's been worth it to me.
Don't believe everything you read that may be to the contrary to your experience--everyone is different, everyone's body reacts uniquely to chemical changes introduced by medication. I wish doctors would take that more into consideration before hiding behind the 'facts'.
Take care, and let me know how it's going for you.
