I take 200 mgs a day of lamictal. I was at 100 but I was also on depakote. I was taken off depakote because of side effects. My doc then raised the lamictal to 200. I am not sure if it is working good or not, I feel myself slipping a little. I use to been on 4 psych meds now I only take 2. Lamictal and paxil. I have only been on these two meds for a month. We'll see what happens.
