Thank you everyone for the replies. I wanted to give a quick update before I get some much needed sleep LOL.

My son had his sleep deprived EEG this morning. Wow what a task trying to keep him awake from about 3:30 on. We did it though. He went a full 24 hours without sleep prior to the test.

I did not stay in the room as I was afraid I would be fidgity and bother him. I asked him about the test and he definately fell a sleep. The only part he really remembers is the stobe light. It brought on colourful spots with eyes closed (did that with me too when I had it done-we are both migraine suffers). He said the fast strobe did not bother him but the slow strobe did.

He said the slow strobe made him feel anxious and scared and he didn't know why. Anyone else have that feeling? He sees his Neuro mid October for a followup.
