I was on 400mg lamictal every day for over a decade. I feel better without it mostly. I stopped it because the tegretol was causing rapid metabolism of the lamictal, and basically cancelling it out. It made some mornings a lot rougher after the tegretol was added, because I'd be way too sleepy. Before the tegretol I never noticed a better or worse if bipolar symptoms with or without lamictal. After I read all the things it can do to your body when you're on it for a long time, I was grateful to be off. I have no motivation most of the time since I stopped lamictal, but I feel better about it, if that makes sense. Probably not.
