re: Any CPAP users in here?

One other thing I'd recommend is seeing if you can get an auto BiPAP instead of a CPAP. With a CPAP you have one constant pressure. In my case, it lead to me swallowing air throughout the night and I'd end up with a bloated stomach and constant morning farts for like 30 min after I woke up. There's a name for it (Aerophagia).

With auto BiPAP, the machine has two pressure levels, high for inhalation and low for exhalation. The auto part means that it adjusts you pressure levels throughout your sleep. Cool thing is, once it's on, it almost breathes for you and breathing against it is no issue. It also eliminated the aerophagia.
