I am curious as to see if anyone has any advice on how to go through the night sleeping absolutely prone; with the goal of keeping my face parallel to the ground. I am willing to move my mattress around, cut holes, do interesting things with pillows, etc. I've tried sleeping on a massage table with my face through the face hole, but it was pretty uncomfortable.
Basically, I have had several sleep endoscopies, surgeries, etc; I'm waiting to have a floppy epiglottis ablated/cut, as it causes me to choke in REM, and it tends to collapse even more dramatically with CPAP usage (the CPAP basically blows it straight onto the larynx). My last endoscopy revealed that the prone position exposes a clear airway, but I've had trouble figuring out how to stay in this position through the duration of the night.
I've had some interesting ideas with tying myself to the bed, etc.. but would rather solicit advice here to see if anyone has any better ideas.

Thank you!
