I hate that mask sometimes. It wakes me up at night and I just want to pull the hose out and throw the damn thing on the floor. This mask I now have to live with to control my sleep apnea. It covers my nose and I have to keep my mouth shut at night while cold air assaults my nostrils. Oh, the endless joy. Here is my experience with sleep apnea. I hope It will help you if you have the condition, too.
