The only EEG's I've ever done have all felt like the same type of ones - shorter in nature, sleep deprived, and generally about 2 - 2 1/2 hours for the study and of course half of that is generally getting all the equipment on (depending on the specialists experience).
I HATE the strobing light part of it. I don't like EEGs in general. I hate them, but they aren't painful, of course. I've never had convulsions during one.
Generally when they do the strobing light things...since I can usually close my eyes, I sing a song in my head or something just to get through it. It feels terrible in my mind, even though I don't have photosensitive epilepsy. However, I still believe I am affected by flashing frames if they are above a certain frame per minute or something. With strobe lights, even as a kid, like on Halloween and stuff, I always felt like I was dying is the best way to describe it because it was all in slow motion, but I would get so lightheaded and foggy. I can't stand it when the kids do their little childish thing of trying to flick the lights on, off, on, off, on, off. I know it's a curiosity thing, but I have to explain that this bothers mommy's head and eyes. I often times wear sunglasses in the grocery store - all the fluorescents make me feel awful sometimes - there are days that I'm fine and days where I feel like I can't keep my eyes open in the store with all the bright lights and feel normal.
