body position and areophalgia

I've had a problem all year with having my tummy fill up with air and I've made and interesting discovery that might help someone else.

I've found that when i sleep on my left side or on my back I will have the problem with swallowing air. When I'm sleeping on my right side it goes away. I would suggest anyone with this problem pay close attention to body position and try to determine if there is a position that will stop it.

I wake up when I've been doing it for a little while and it took me some months to figure out what was going on. The bad part is that it just isn't comfortable to lie in the same position all the time so I know that I'll probably never sleep a whole night with the mask on. The good part is that I at least have a way to correct it and I can make sure I always go to sleep in the optimal position.

My next plan is to do some scientific studies involving my pillows. I'm guessing some of them are better than others for sleeping on my back or left side.

I've been a hosehead since July and my CPAP pressure is 19cmH2O. My experience differs a little bit from yours. I find I get serious bloating if I lay on either side, but not so much if I sleep on my back.

I also have less bloating if I sleep on a flat pillow (made for a back sleeper) than if I sleep on a fluffy one (made for a side sleeper).

Let me know how your pillow experiments go.
