I've been using CPAP for 10 years, and it's pretty much the best thing that ever happened to me!
The morning after my first real sleep in ~5 years was an unreal improvement. It felt like I was snatched from my death bed and back to normal.
I use the nostril mask, and it doesn't really bother me. The full face mask experience is a lot worse.
PS Technically, it blows!
