Maybe you should consider not driving at all until this whole thing gets resolved. It's not worth the risk. Hopefully you'll have better luck with this new neurologist and he can find the right cocktail of meds for you.
When you were a kid and you told yolr parents about this "Head thing" they probably thought that you were making it up for attention cuz there wasn't a lot of info around about seizure conditions at that time.
Good Luck, hope your next appt. is favorable.
