My first sleep study was about 3 weeks ago and after two hours, the tech came in and told me I 'met the criteria". He put a CPAP mask on me and I slept well for the rest of the night. He was not allowed to say how severe it was, but I thought that was the last of it. Imagine my surprise when I got a call wanting me to schedule another sleep study. Didn't do so well on this one, as I slept well on my side with the mask, but he needed more data as I slept on me back. I couldn't get back to sleep for the rest of the night. He told me as he unhooked me in the morning that the Dr. may want a third study, as he would not put me on the table if I had a chance to stop breathing, so that terrified me. Turns out, they're going to intubate me, as they do everyone else on the table, so this is not a concern any more. I got a call from my PCP today telling me that someone would be contacting me soon to schedule an appointment to fit me with a mask. Crisis over. The mask didn't bother me as bad as getting woke up no less than 4 times during the 2nd sleep study. I think I'll be able to get used to it.
