After the surgery, I had to surrender my driving license; I was able to get it back after a couple of years with no evidence of seizures. All well and good.
I'm sorry to read of your medical journey, Alexander; however, glad you are out of the other side of it. With a little luck (I say luck because dealing with the DVLA requires it!), you'll be reissued your license soon and we'll have some fine weather in October (roll on Indian summer!).
I had a friend who got to 23-months and then had a very minor seizure, as he was honest, and reported it, the clock restarted and he had to wait another 24-months. Thankfully the second run was clear but we made sure to celebrate when he was able to get back behind the wheel!
