I am so glad to see this thread! I was 1st diagnosed with sleep apnea 6 yrs ago. I started on the CPAP at that time. When it works well, I sleep and feel fantastic. The problem is some of the side effects. Sometimes, my stomach gets bloated and distended and it is so uncomfortable! Spoke to my Dr. about it and said we maybe need to tweak the settings. So I just had another sleep study this past Sunday. I am excited to hear about the new quieter machines...
