My first night with the Full Face mask was terrible and only got 3 hrs sleep (my estimate). I spent most of the night fighting with the mask, but stuck with it for 7.5 hrs. I finally got it right and the last 3 hrs actually felt quite comfortable.
The second night was a dream, no pun intended. It was the first time since I was a baby that I didn't have to climb out of my bed (crib) once or twice during the night for a pit stop. I felt pretty rested that morning. Last night was the same. My AHI was 1.2, 1.5, and 1.7 which I believe is a good thing.
I'm learning a lot from this forum and like my subject title says I wish you all a Happy New Year! Sleep tight!
