My DH also has sleep apnea. I used to wake up at night and realize he wasn't breathing and have to shake him to get him to breathe. Very scary stuff. He is doing fine now. But I have developed a severe snoring problem ( my roomies at the last quilt retreat confirmed my DH's comments about my snoring!) and have been exhausted during the day so I go tonight for a sleep study. I'm kind of creeped out about strangers watching me sleep...
