I understand exactly what you mean. It can be a scary thing to get back out there driving after learning you have seizure-disorder. In my state you have to be seizure-free for 6 months before driving.
Can I ask if you have an "aura"? That's a warning that you're going to have a seizure... because i do, it helps. i usually have about
a couple min. to lay down or get in a safe place.
Also, once your medication is regulated it will probably calm your nerves a tad also. But because of this i take extra precautions and keep more space than normal between me and the car ahead of me, etc. mostly because i feel the medication slows my reflexes down some.
When u are able to drive - i'd take it slow. only go where you have to until your confidence is back.
Have you only had 1 seizure? Are they doing any testing?
seizure disorder - chronic myofacia pain - B-12 anemia - severe neutropenia - bulging disk in neck, etc.
