Stomach and bowel full of air

Does any one else wake up with air in their stomach and bowel and if so how to prevent it from happening

Are you new to using a CPAP? I found I struggled with this at the start but it got better after the first few weeks. It's caused by swallowing air. Once I adjusted to the machine it seemed to mostly go away but occasionally it still happens to me. Like last night when I was stuffy with some post nasal drip it was bad again. Perhaps in part because I'm swallowing more with the post nasal drip but also I suspect from the pressure increasing because my nose was stuffy. They say a chin strap can help which I use. I also find it's worse when I sleep on my back so I try to avoid that. I also find it helps to take a GasX in the morning when it happens.

Last night was my first night...and I'm still burping even though I have been up for 3 hours now. I have done a lot of reading, and it apparently does go away after a while. I do wish there were some way to simply stop it from happening!

Can't help with this issue as it only happened to once in the years I have been using PAP therapy. Nothing out of the ordinary but I recall I awoke in the middle of the night and the word burping doesn't describe what my reaction was. More like volcanic but it was pretty much all at once and a one time deal. It would have been funny if I had a witness videoing the episode but I was alone in my RV when it happened. Honestly it was kind of scary and I have never read of anyone figuring out why or how to stop this issue. Good luck and I hope this issue mitigates over time.
