Digestive Issues & Twitching

If in the 4 months you've been off CPAP you still had digestive symptoms, by all means let the doctors do a thorough job of checking you out. If the problems were only when on CPAP, there are some things that can be discussed to try to mitigate the problems. Hard to say anything more without more information. Do you have a copy of you sleep study report? There may be some info in there that could be helpful going forward. Regarding the twitching, does your report say anything about limb movements? Can you be more descriptive about your twitching? Have you had your magnesium level checked? Unless aerophagia is a major issue with you, hopefully you can get back on your CPAP treatment and get it optimized. Sometimes a few tweaks is enough to improve the experience. We just don't have enough information to offer help with that yet. Good luck going forward.
