I am a fairly new cpap user (2 months). I too suffer from aerophagia. We've decreased the pressure from 11 to 9 but it continues. It is very painful along with belching and flatulence. In fact, it is so bad that I have temporarily discontinued use of the cpap. Someone mentioned the LES may eventuall...

Can someone tell me where to find information about noise levels of c-pap machines? I'd like to be able to compare before I purchase.

Thanks, Terry
