hi freewill,
I used a CPAP for over 10 years. It was wonderful because it allowed me to get refreshing sleep. The day it was delivered I hooked it up and took a nap in my recliner! The mask seemed odd at first but I got used to it easily. The quality of my sleep improved so much. I was very surprised and I felt much better and my sleep was improved much more than I expected! I think you will like it too.
Like with many things, you may need to try different masks/mouthpieces until you find the one you prefer.
I no longer use it since I quit smoking a year and a half ago and lost 90 lbs in the last year. However I keep in close by and used it temporarily when I had to be on narcotic pain meds that caused my symptoms to return.
Good luck and let us know how it goes.
