I have been using a CPAP machine since March and I an still getting use to it. I had one heck of a time because when I did get use to the nasal pillows then I couldn't get to sleep with it on. However I am doing okay. I had three nose operations and the throat operation but none of them worked for me. The throat surgery was very painful which the doctor warned me about and I'm sorry I ever went through with it. Maybe someday they will invent an easier way to keep our passage way open.
