KT, I have had several friends with epilepsy, most of them drive and lead perfectly normal lives, they just have to take med.
One friend developed epilepsy related to a head injury from a car accident. Since then he has gone on to do Race Across AMerica 7 times and holds the 2 person mixed team record with his lovely wife. They now have a 9 month old daughter and he's training for a 575 mile race coming up in October.
They'll get it all sorted out. It'll take some time but you'll be able to lead a very full life.
Living life like there's no tomorrow.
