I woke up at about 1am with a lot of stomach pain, and didn't really fall back asleep until 3 or 4am. It turns out it was gas and bloating from the CPAP, although I was considering going to the ER before I realized that (and might have, but the pain was general and not localized, and I've already had my appendix out).
After some burping and walking around I was eventually able to get back to sleep.
I got some gas-x today that I'm going to try tonight, but I'm a little worried about going to bed tonight. I know I'll feel better and more awake tomorrow if I use the CPAP, but I'd also rather not wake up in pain again.
Is there anything else I can try? Has anyone else had sudden bloating? I didn't have a problem up until last night - in fact, I thought it was remarkably easy to adjust to using a CPAP.
Quick edit: I have EPR turned on and set to 2. I'm also going to try increasing it to 3 tonight.
Also, looking at the data from last night in sleepyhead shows nothing out of the ordinary. My pressure went up to 9 a couple times, which it's done lots of times without issue.
