I've been around a lot of seizures, but one of my friends gets em when he's off his meds (money reasons), he's had some success controlling them by sleeping as much as possible, but he's actually had 2 behind the wheel, if he has another seizure behind the wheel, he'll lose his lisence forever.
A lot of seizures are not that violent, when most people picture a seizure in their head, they see someone having a Gran Mal seizure, but there are all different kinds, the oddest I've seen was a narcaleptic seizure, when the kid just froze up and stared into nothing for a good 2 minutes.
