I can't tell I'm taking anything at all at 25 mg. I'm at 150 mg and it's fine. I'm in some wierd ultraradian cycling mixed episode thing, so Lamictal alone isn't controlling it at the moment. Anyway, I get some mild side effects at 200 mg. Dizzy/lightheaded. It's not as bad as the dizzy/lightheaded I get with an anxiety attack.
Maybe you are getting sick?
