C Pap machines Do you have any advice on how to get started on one?

I have ignored sleep apnea studies for years. We all snore. I think the world has advanced sometimes for the detriment of our society and for the pocketbooks of technology. So I got a darth vader mask today. A smaller one but had to go over mouth, because I tend to keep that hole wide open.
Do you feel like you cant breathe getting used to this crap?
Help…..Luke, I am your Father.
