[Equipment] New Mask - Horrible Night!

[Franklyspeaking]

Hi,
I've been on CPAP Therapy for three months and using a full face mask with great success. I decided to get a PR Nuance Pro as an alternative. I believe the pillow size and strap tensions are correct. At bedtime, I made sure the tension was just snug enough to provide pillow contact with my nostrils and then went "lights out". The contact pressure on my right nostril was painful! I tried using a water-based lubricant, which provided some relief, but just made the pillows more likely to slide out of position. Tightening the straps to correct this only lead to more pressure on my nostrils while allowing the pillows to slide out of position.

The pressure and slippage issues became so intense last light that I ripped the make off and went back to my full face mask after five hours of struggling.

My machine is in APAP mode, with pressures typically 6-7 cm H2O.

Has anyone on this forum had a "first night" experience like this? If so, what did you do to correct this? If this is just "normal", does the pain//irritation just go away after a while?

One other thing I wanted to mention is that I purchased a CPAP pillow to sleep on. It was about $60 off eBay but it really helped to not move the mask when sleeping on your side and reduced the red spot on your nose ridge.
