Hi Nelie,
I had a horrible time with the mask when they made it and fit it. No one had explained the process to me and it was terrifying. I didn't like being restrained that way. So, realize that you will be very restrained and the first fitting takes alot longer then a regular treatment. After the first week of so of treatment I adjusted and found ways to deal with my anxiety and by the end of treatment I was like Gary, I could have fallen asleep!
Get a PEG if possible.
I had hyperbaric when I needed a tooth extracted and I had no issues at all.
Hope this helps,
Minnie
