while wearing the cpap with the nose plugs (not the face mask) phobia & will not wear it. I awoke suddenly and coul dnot breathe, sweating and heart pounding. I attributed it to my opening my mouth while asleep. Scared me silly. I tried again to sleep, same thing happened tht nite and for the following two nites. I was given a chin strap to try & hold my mouth closed, which did no good. Finally, I just gave up on the machine, since I wasn't getting any sleep anyway. Any suggestions?
