As far the seizure itself, I have no memory of what occured during it. I've been told that a seizure is not a pretty site to see and that a person is better off not seeing himself have a seizure. Yes I will have memory loss for a days after the seizure but then after a while little things will come back to me. I can not say that Dilantin has anything to do with it. But it does damage to your gums though. I do know that I will repeat myself once in a while without knowing it. My Dr. has said that this is one of the effects that Epilepsy has on the brain.
