Be honest with your doctor. Two seizures in one day is something she needs to know about most definitely. Hoping it won't happen again (and I'm with you as far as hoping it won't) is okay, but not to the point of denying that they did happen just now.

You don't want to be driving and have a seizure and possibly hurt yourself and others and then have that regret to deal with.

Keep working with your doctor who wants the best for you. Have you told her that you refuse the neurosurgery because you are afraid? I am not minimizing your fear at all when I say that I would imagine anyone who has had the surgery was very scared too. Have you talked with a neurosurgeon about the surgery, to learn more and to hear some reassurance from the person who knows most about the surgery?

Tell your doctor so she can help.
