I have been using CPAP device for nearly 9 years. To begin, any Dr or sleep specialist who tells you by using CPAP you'll get the best sleep of your life is blowing smoke. I started with a solid plastic nose piece but found every time I moved my head even slightly, the seal would break and the hissing would wake my wife. After several adjustments I learned of the Dreamwear nose cushion. It can be used with either pillows which have a flange-like pad that sits just inside the nostril, or there is a pillow that rests on the upper lip just below the nostril. the pressure setting allows for air to gently blow into the nose to the back of the throat and out the mouth keeping the airway open. It attaches to the head by a soft very flexible head piece, and the air is supplied via a flexible hose attached to the top of the head gear. Thus no snoring. Nevertheless, I still need to adjust once or twice throughout the night. It works, but its not great. If I do not wear it I am guaranteed what I describe as panic dreams where I am in crazy situations and gasping for breath. I've read, that is my brain telling my body to wake up.
