Yeah I hate the mask.Wake up yanking the thing off sometimes.
I don't like trying to find a position where the pillow won't push it out of the way, but I love it. My quality of life improved 1000% when I went from waking, on average, 90 times an hour before it, to actually getting some sleep.
My night brace, on the other hand, used to show up under my pillow in the morning. I'd pull it off without even waking up. My father, who was also my orthodontist, really didn't believe I ever put it on. But I did -- at least a couple of times a week.
