It's been hard dealing with epilepsy.  I've had the condition my whole life.
I hear the seizures can vary from brief but could last a long time.  How do you deal with them?
Other than making sure I take my medicine, I try to avoid events that trigger my epilepsy, like flashing lights and loud noises.
That has to be tough avoiding flashing lights, especially if you are driving at night.  
I can at least prepare for those conditions.  What gets me most often is video games, which I love.  I have to be prepared to look away at a moment's notice.  I make sure to keep the volume low, though
Does it help to play video games with a lot of lights on (instead of playing in the dark or low-light), or does that not make any difference?
It actually does!  That's something one of my doctor friedns told me to try and it really helps.
Are there certain video games you prefer to play to avoid symptoms of epilepsy? 
Yeah, Action games and Shooters.  So I like games like SimCity and games without much onscreen action.
