Does your machine have a humidifier? Maybe crank it up more?
Do you have full mask or just nose?
So I slept with the machine for the first time last night. I am unimpressed. I woke up (all the way) more often than usual. My nose was stopped up and dried out and the mask hurt the top of my nose. Oh well it has to get better, maybe a different mask.
It does have a humidifier. Full mask.
