Yeah of course. Especially while I didn't have an alternative yet. I have this machine for a reason and untreated sleep apnea is also dangerous long term. It's also very hard to live while sleeping so badly.
I'm not using the bad one though. The one that smells and blackens face masks. Only the other one. I regularly let it blow into a mask for a day to verify.
Yeah, oral appliances don't fix the actual problem: tongue slacking into the back of the throat. It's the same reason a chin strap will just make you choke.
Supposedly you can "train" your tongue to stay in position with tongue & jaw exercises, but I saw no effect.
