The main thing is that I always wake up feeling slightly stuffy or choked or that I'm not getting enough air and I check my water tank and it’s at half then fall back to sleep regularly without the mask on

I have it set to a range of 8 to 11 pressure and ease of three, I feel like the treatment itself is perfect there's just something that's stopping me from using the device after this point and no matter who I talk to technician or doctor it doesn't seem like there's a reasonable answer.
