CPAP user here, and "have you tried taking up the didgeridoo" is comfortably the best sentence I've ever read in a medical journal. The mask works fine — it's just that I go to bed every night looking like a minor Star Wars character, so I'm very open to alternatives. And from the other comments, the didgeridoo sounds like the boring tongue exercises in a trenchcoat: same throat muscles, except you might actually keep doing it. Which is the entire problem with the tongue exercises. Study was moderate apnea so I'm keeping the machine. But I am absolutely buying a didgeridoo and becoming insufferable about it. My household has been notified.
