I have (sensory) simple partial seizures on and off, but they don't interfere with driving. I get an overwhelming feeling of deja-vu, or fear when I have one. I'm always awake and alert through it.

Even when I have a Gran Mal... (only 8 in 6 years), they all happen while sleeping on my back, due to sleep apnea. I'm on only 300mg/day of phenytoin for the GM seizures, and up to 2mg/day for the anxiety and simple partials.
I still get to drive... just not while I'm asleep. :eek:
I understand completely... I'd be lost without my car.
