I can say with no hesitation now at 200mg lamotrigine i feel so much better than the 400 I had been on for a very long time .... I did not even realize HOW MUCH it had deadened me till now that I am on a lower dose ... more energy and a better "outlook" on life ... I like it .... but it is a good med if you need it ... and I expect to always be on it ... just at as low a dose as I can go ....
