I've taken trileptal for two years now. It definitely works for me although the first 6-8 months were an adjustment. I was very drowsy in the mornings, gained some weight, had trouble with coordination, and some muscle spasms (tardive dyskinesia?). However, I'm doing much better now. My weight is under control and I no longer get unmanageably drowsy -- at least nothing a good cup of coffee can't cure. The muscle spasms come and go, being most prominent when I'm stressed. Not a big deal but I didn't have them before I started trileptal.

Good luck!
