Answer: My husband has a C-Pap machine and it helps him loads. It will take a little getting use to but the benefits are worth it. He found through trial and error that he is most comfortable if the machine is above the bed (on the headboard). It allows the tube to move more freely when he goes from one side to the other and since he likes to sleep on his stomach it allows for some of that also. Keep the mask part clean or it will develop an odor and good luck and good health.
