Thanks guys. I have found my pharmacist and doc to be less than knowledgable about side effects. They've told me several times "no, that is not a side effect" and then later they say "oh, sure that can be a side effect". It's a real pain in the butt.
I think the problem is my doc might only have 30 or so people on Lamictal. So probably no one else has my side effect.
I did find a couple of people on the web with thrush from it and quite a few with vaginal yeast problems from it. I hate to switch it but I may have to think about it. I think it's that whole skin rash thing...only in your mouth.
