If I were to tape my mouth closed at night, I'm confident I would die. Other comments are mentioning liability and not running your own CPAP, but this is exactly the kind of advice that should be put before a doctor before doing.

You will wake up if you need to breathe. Otherwise people with sleep apnea would die. They don't. They just don't sleep properly.

People with severe apnea die from it all the time. You'll wake up if you need to breathe...until you die of a heart attack or stroke from all the damage.

Pretty clear he meant death from suffocation.

[caymanjim]

Suffocation is what causes the heart attacks and strokes. It's what killed Carrie Fisher. Granted, she had chronic underlying health problems and was apparently on a bunch of drugs, but the proximate cause was apnea.

[schwartzworld]

Most people with sleep apnea take a big breath through their mouths a moment after they stop breathing. Taping without CPAP is absolutely risky.

Either I die or it's impossible to sleep. These options don't grab me.
