Lamictal caused me to have a HUGE dysphoric manic episode. Apparently, this happens to other people as well, because there's an article on Dr. Goldberg's (Depression Central?) site about Topamax (I think) working well for people who become manic on Lamictal. It seems you mostly hear about people loving this med, but it can have it's dark side, too. I think it screwed with my hormones, because I also did not have a period the whole 3 months I was on it, but then started 3 days after discontinuing Lamictal. The rage left at about the same time.
