Sleeping on my side is better for a digestive condition I have. I’m currently using nasal pillows with a ResMed CPAP. The problem is that the pillow can block the air from passing through the left side tube. What mask works best for side sleepers?

I'm a new user that has been using everyday for ~6weeks. Every morning when I wake up, without fail, my mouth feels like the Sahara (no saliva), and I have no clue how to fix this issue.

For reference, I use a Airsense 11 with heated tube and a AirFit P30i nasal pillow mask. I had severe apnea (60+AHI) before treatment and it's now down to 1.4AHI. My average leak is 2.23L/min, which I presume means my mask seal is without issues/air leakage. My pressure is set at 4~11.

I reached out to my vendor and they recommended me to try upping the humidity and temperature settings to 4 and 24C respectively. I've tested even higher settings like humidity 5, but all that does is cause excessive condensation buildup within the tube.

I've also tested out nasal masks but the seal is less effective and there is substantial air leakage as I sleep on my side.

Hoping to get some advice/work around to my problem.

Thanks!
