By the way, you can practice circular breathing very well in the shower. Take water in your mouth and breathe in through your nose while simultaneously spraying the water out through your lips.
It worked
It took me 1-2 years to learn circular breathing, but even just learning to play for 15 seconds on one breath can give the "oxygen high" from breathing so much.
Presumably quadruple reed instruments (that require even more air pressure to play) would be even better: https://en.wikipedia.org/wiki/Quadruple_reed
Attention is magic stuff. Putting it on part of your body can make it better. Withdrawing it can make it worse. I suspect that much disease stems from such neglect.
I used to have a chronically stuffed nose. Then I started doing a kind of meditation where I put my attention upon my nose. My nose opened up and I almost never get a stuffed nose anymore.
"Participants received a standardised acrylic plastic didgeridoo that was developed by the instructor in collaboration with Creacryl GmbH (Ebmatingen, Zurich, Switzerland, and costs €80 (£43; $94), fig 1). The didgeridoo is 130 cm long with a diameter of 4 cm and an elliptical embouchure with a diameter of 2.8-3.2 mm. Acrylic didgeridoos are easier for beginners to learn on than conventional wooden didgeridoos."
When I used to make my own PVC didgeridoos, I would melt candle wax and then dip one end repeatedly into the wax to build up wax layers until it had the desired thickness and shape.

...along with various other videos on that person's youtube channel (he's an NHS Sleep and Ear Surgeon).
Of course, there are lots of underlying causes of sleep apnea that vary between people, so what helps one person may or may not be relevant for others. Seeing a doctor in the field should be your first step if you suspect you are suffering from sleep apnea.
Two wrongs can make a right.
Hope he sleeps well tonight!
You'll hear Charlie McMahon going at it with continuous circular breathing for five to eight minutes or so on the early Gondwanaland albums (along with sliding length didgeridoo effects and 'singing' down tube).
You know who doesn’t have sleep apnea? Skinny people. I mean wafer thin. They only get it from actual constructive nasal obstruction.
Oh, did you make use of the central telephone service did you? You didn't send the list by carrier pigeons?
