Hey my dude I know this is late but I was combing over memes from this page and found your comment. There are dental oral appliances that push your jaw forward so that your throat does close down while you are sleeping, thereby eliminating sleep apnea much in the same way a cpap would. It's less claustrophobic than a cpap!

Mine just goes over my nose. Took some time to train myself to keep my mouth shut, but it works. I've been in a couple places without power and I regretted not having a battery for it in the morning.
