Dittos, been on BPAP since 2008. Lost 40 pounds and now on CPAP full mask. Break into cold sweet if I think something is wrong with the machine because I know how I'll feel in the morning without it. I'm a 100%'er and they can have all the studies they want. For me it works and has given me a better safer life
Plus, my wife is happy. It was her threatening to sleep in another room that was my primary motivation to make the CPAP work.
