My Jeff has a CPAP. It's like sleeping with Darth Vader. He sleeps flat on his back with his mouth wide open, so he kept breaking the seal of the thing, so it would pump air harder in a vicious circle. I would wake up hearing him choking. He gave it up for a while and tried to sleep on his side so that he would snore less. He was so tired during the day that he decided to try it again. This time, he has a better face mask, so he has less problems.
I still don't like sleeping with Darth Vader. The machine makes a humming sound that irritates me, and he has to remember to throw a towel over it because it makes a ghastly green glow in the room that keeps me awake if it is uncovered.
I hope that your wife and dogs can stand you with the CPAP.
Be careful - you might scare the dogs!
