I am on 400 mg of Lamictal daily (200 mg in AM and 200 PM) and have been for a few years. Even though I still have flare ups and cycling (in other words, that's what I'm going through now), I would be so much worse without it. 200 mg was not enough for me. Prior to that, I was having bad, racing thoughts and debilitating mixed episodes. I have no side effects... even on 400 mg. So it's definitely an option worth exploring from my experience. I hope you find relief soon.
