> This may sound crazy, but for those who can't tolerate a CPAP, an effective alternative is playing the didgeridoo.
They linked a study [1] that actually tested this and found it to be helpful.
Was this a problem for you? I have a feeling a sleep medication would help with this but won't that interfere with the study?
At the end of the day, you will eventually fall asleep and hit deep sleep and they'll get the measurements they need.
No one sleeps well knowing they are being watched and hooked up to all those sensors. :)
It's possible that you're experiencing collapse in both areas; and it's also possible that neither device will work, depending on the severity of your sleep apnea; namely if you're overweight. I had "mild" sleep apnea that left me VERY fatigued because it was characterized by mild hypopneas (slight secessions in breathing) at an incredible frequency which stopped me from reaching REM throughout the night. The devices helped.
To ameliorate the situation completely I found a great doctor out of USC who ended up performing 4 procedures and 3 surgeries. I had my uvula cut, my tongue burned, my palate ablated, and a few other things. It was an incredible headache during the time but well worth it and now don't need a CPAP. Also worth mentioning that I had some gut dysbiosis at the time which can masquerade as sleep apnea. Good luck to you.
