Anyone try nose breathing to eliminate sleep apnea

Ever since I focused on breathing through my nose, my wife says my snoring and sleep apnea is a lot better.

No CPAP machine needed.

Anyone else try this?

Yes, kind of, but I cheat and also use a CPAP. I use a chin strap and paper medical tape over my mouth to stop me from opening my mouth during sleep. That is in addition to using a CPAP with a nasal pillow mask however. I suspect it may help with snoring, but unless you wear a CPAP I am not sure how one could tell to what degree it helps with apnea. See this video about mouth taping by a dentist.

Mouth Tape for a Better Sleep

I'm not sure how your wife would know that your sleep apnea is actually better. I haven't snored since I had my tonsils out as a teenager, but I still have sleep apnea. My parents wrongly assumed that the fact I wasn't snoring meant it was no longer an issue. I only figured that out years later through a sleep study.
