Hello ferrells ~ First I'll say that I'm so sorry about your son's seizures and the things have gone with them. I understand how difficult that must be.

I'm so very much older than you are that I probably don't count with your son's trials with AEDS, but I took Felbatol for maybe a year after it was first introduced and I had no trouble with it. My neuro jerked me off of it when the bad news about it came out simply because I was having no good news on it either.

There are so very many AEDs available. Has your son tried them all?
