Will I be able to get my driver's license?
Yes, if you are not having any seizures that make you black out or lose control of what you're doing. How long you have to be seizure-free before you can drive depends on which state you are living in. The time ranges from three months to a year. You also have to make a real commitment to take your meds every day, on time, so you don't risk having a seizure on the road.
I've had a couple of seizures but I don't want to tell my doctor because I'm afraid I'll lose my license.
If you don't tell the doctor, you're missing a chance to adjust your meds so you won't have more seizures. The bigger risk is that you'll have a seizure while driving. While it's tough not being able to drive for a while, you don't want to risk having a bad accident that hurts you or someone else.
If I lose my license because of seizures, can I ever get it back?
Yes. Once you have been seizure - free (really seizure - free) for however long your state requires, you can re-apply and get your license back.
