At least you get some sleep the night before your sleep deprived EEG. I had to stay up all night prior to the EEG. Then, as they were trying to do the EEG and told me to go to sleep, a construction crew was pounding on the wall. Not possible to go to sleep with that racket. The tech complained and got reprimanded for interfering with the construction crew. Needless to say, my long night awake was a total waste.

We did determine that I have a problem with Central Sleep Apnea. As I would relax with my head supported by a rolled up towel so the electrode contacts would not be disturbed, the neck position caused me to stop breathing if I relaxed, even when I was awake. No snoring or breathing sounds at all. I would just relax and stop breathing. I believe it is due to an undiagnosed neck injury causing inflammation in my brain stem.

Of course, doctors are not interested in checking this out.

Hope you can fall asleep when the time comes.
