What is all this talk of C Flex and Auto

[Sleepless on LI]

You are an angel. Thank you so much for taking the time to write such an informed and enlightening post. You really must be a wonderful woman. You are so willing to help and you really seem to know your stuff. I really appreciate the time you took to impart your information to me and everyone else who read this.
I found out today that I need a pressure setting of 10, which I have heard is not that bad. My doctor is going to write on the script for a machine with heated humidification, which I am relieved about. However, I am still leaning towards the Oracle, at the advice of a friend of mine. I guess you can always change your mask.
How long have you been a sufferer of OSA and how long did it take you to get relief? I can't tell you how discouraged I have felt reading all these different posts and how confused it has made me. I like being in control, especially when it comes to medical issues. But this is something so foreign to me. I hope one day to be as well versed on this subject as you are and will come back to help others as you have helped me. Thanks again.
