Cindirella60 post was right on! You must have your head adjusted correctly to the pillow in order to get it to work. When used correctly the pillow causes your head to tip forward, thus making it almost impossible for your mouth to open and snore. You than breath through your nose. I sleep much deeper than before and no longer are sleepy in the daytime. The pillow needs to have user instructions, because I used it incorrectly for several nights. It helped me and is worth the money!
