I take Tegretol. It's not the first drug of choice, but it also treats my facial pain. Some people take Lithium, but I have avoided it because I don't like the potential side effects or the need to have bloodwork done frequently. But it might have to be an option for me at some point......

Lamictal seems to be the one favored by docs, but I had to go off of that, too, after many years.

Let us know what the doc suggests!
