Seizures

[scareyme]

I started having grandmal seizures around 1990 I would be on meds for a while then for one reason or other quit taking them. Sometimes I would go a couple of years without having one. Three years ago Ihad one in my sleep and broke a couple of ribs. I didn't realize I had had a seizure though since there weren't any other signs that it was a seizure. So I just forgot about it, I almost always had all my seizures while sleeping so it didn't bother me too much. Then last year I had stopped at a SuperWalmart on my way home from work, and I started feeling funny, lightheaded, everything started getting darker or brighter I started trembling all over so I tried to get to a check-out lane asap well that's the last thing I remember till I woke up in an ambulance and couldn't even remember my own name etc, I had busted my head open in several places so I was taken to a hospital.
I am on Keppra and have been since April of last year, I was doing good up untill a week ago now I've had several episodes while driving and and or grocery shopping, I'll start getting all of the signs that I'm going to have a seizure and it's like my brain is misfiring or something, I'll start sweating, and heart will start pounding and I can't concentrate, what ever I look at starts jerking around like when the satelite is loosing a signal on the tv it's crazy, but, I don't fall out. I'm aware of it. Has this happened to anyone else before? What is going on? I haven't had a level done on my med's so I have scheduled an appt with my dr. I just hope I'll be able todrive there without killing myself or worse someone else.
