Coming from someone who has had a history of seizures, they certainly aren't anything to play with. That said, in most cases, with the right medication, these things can be controlled. I take Phenytoin at night. I still sometimes get what they call these myoclonic seizures from time to time. They aren't bad. It's like a split second jerk movement of the body or like your muscles all tightening up at once for less than a second. So if you were holding a cup, you may drop it, but thankfully, I've only had a 3 grand mal seizures.
It does sound like things are going well for him. He's officially listed as questionable for this week, but still needs clearance.
