I did not expect comfort, but I never dreamed it would be this bad. I fitted it via directions as best possible. It constantly fills with saliva keeping you awake. When I finally had enough sleeplessness (perhaps that is the object, if you don't fall asleep, you cannot snore!), I removed it to realize the unatural position had caused my jaw to cramp up. I could not close my mouth for several hours. Had I slept with it in all night, I would have not been able to eat breakfast.
