My DH has sleep apnea also. He also does not snore anymore. He stopped breathing 117-120 times an hour also. Every time he sat down he would go to sleep. He would also doze off when he was driving. That was the last straw for me. I finally talked to the Dr and told him what was going on. Doc ordered a sleep study and the rest is history. His machine is quiet. The only time he wakes me up is if his mouth comes open...then we are talking "wind tunnel" LOL
