New to CPAP - Advice from experienced users would be welcomed

In for surgery this evening my time. Will need to stay overnight and during 2 week recovery period will have initially no ability to breathe through my nose, which I am dreading. I'm having correction of my septum, turbinate reduction, and removal of cysts (which need to be tested). ENT doc says this is the other half of the equation with CPAP only giving me 50% of what I need. Congestion needs to be corrected for CPAP results to be optimized.

Good luck.
