Possibly photosensitive seizures?

Hello all,

For the past few years I've noticed I have these occasional...things that happen when I'm exposed to rapidly flashing lights. It doesn't always affect me when I'm on the internet and see something of that nature, but it does make me feel a little sick and have to click away.

Anyway, I first noticed it while in highschool. I was walking through the halls on our outdoor campus, and the rails of the second storey had lots of large holes as part of the design. I've always been a fast walker, and the sunlight flashed through it rapidly enough that I physically stopped moving for a few seconds, my vision went black, and I couldn't move. Then I snapped back out of it and kept walking, but I was really freaked out.

Nowadays, since I graduated a couple of years ago, I notice it while I'm in cars, too. It only happens when the sun is low enough in the sky that, while driving, it flickers through the trees. I've learned to put down my visor or put up my hand to shield my eyes from it, but it has happened on multiple occasions.

I'm now on a new medication that raises my risk of seizure (Bupropion) and I'm concerned. It hasn't happened in a couple of months, but I neglected to tell my doctor about it before she prescribed the drug because it can be so few and far between that I just sort of forgot.

I'm worried I won't be able to drive if I'm diagnosed with some form of epilepsy, because I'm very independant, but I guess that's the least of my worries.

Anyways, can anyone tell me if they've experienced anything like this before?
