I don't suppose your sleep specialist elaborated? Suffocating in your sleep is really hard, this is why people with sleep apnea don't just die instantly, instead we start to feel awful over a very long period of time. Your body wakes you up when your breathing is compromised (usually in response to an increase in CO2).

Guess they're just covering their arse with that advice.

Also, when you're on nasal CPAP, and pressurised air is being blown into your nose, you'd have to have really weird things happening to suddenly get a nose that's completely obstructed in spite of the pressure....
