Hello, I have had sleep apnea for about a year and a half. I had my gastric bypass on July 25, 2012. I have been told that my apnea should be cured as well after weight loss. I am looking forward to that, but let me tell you, I also use the mask with the pillows and it is so much more comfortable. When I was tested, I had the opportunity to try both, to see which one I liked better, and of course the pillows were better. I got used to it very quickly and it is not a problem at all. My machine also has the "amp" feature, that slowly increases the pressure so as to not blast you from the get go, so that also helps the comfort level. The machines are fairly quiet, I travel, camp with mine and have never had a problem. I'm comfortable with it, but am looking forward to not using it anymore once the weight comes off!
