I too have sleep apnea and I have worn a c-pac for 5 years or more. Once you get use to it you would never think of going without it. Sleep apnea doesn't just go away after 2 years of being on a c-pac and the operation will only work if you lose weight and it is a very terrible operation. Going without your c-pac when you have apnea can cause heart failure. Just get use to it and accept it and your days and nights will be better for it. Good luck with it.
