  1. I was doing fine with my CPAP for a year now and all of a sudden I am getting severe stomach pains and incredible gas. The machine he is set for the lowest pressure setting! Very disturbing.

  2. I’ve been using my CPAP for about 3 yrs..but that was off and on because I just couldn’t get used to it. Now I’ve been using it faithfully for the past 2 months..but have been really gassy! I tape my mouth sometimes so I don’t get air or dry throat. It is set at 17 & leaks alot, so it keeps me up at night..feeling tired all the time. What can I do?
