Hi, Tracy,
For a video EEG they'll wire you up with electrodes like they did for a regular EEG, and then they'll confine you to a nice padded bed with a camera aimed at you. You have to call the nurse to help you use the bathroom, or do most anything. It helps to have a family member there to help out, too. Towards the end of my stay my doc let my mother help me to the loo, instead of having to call a nurse.
They'll do everything they can to provoke a seizure. They'll stop your meds, sleep deprive you, make you breathe funny, flash lights in your face. If you have any seizure triggers now is the time to trot them out. I wish I had smuggled in a triple martini. I'm sure it would have done it for me. Do you have any that you can control, like caffeine, extreme emotions, alcohol, a food or chemical, etc.? Pack it just in case.
Also take your favorite pillow, lots of books and music, a laptop if you have one, games, and a list of your friends' phone numbers. Also about a half cup or so of olive oil, to help get the glue out of your hair. You rub it in and work the glue globs inbetween your fingers. It takes about a half hour, but it works better than most methods.
Hang in there. It's not all that bad. Nothing hurts. It's just mega boring.
