Sleeprider, I have done as you advised. Thanks!
edit: I'm going to add another observation. I couldn't feel the machine ramping up from 6 over 5 minutes... after about 10 minutes, I got up and looked at the pressure and it was over 10. With A-Flex on 2, Humidity on 2 out of 3, and Tube Heat on 2 out of 5, (house temp 72º) 9 to 11 centimeters honestly feels like I'm just breathing like I did in my twenties and thirties, without a machine. I wake up neither wet nor dry mouthed, and for the last 3 nights, haven't had to get up to go to the bathroom. I am absolutely loving CPAP!
