Hello you two floofers! ?
The opposite is the case: you'll wake up, even if heavily intoxicated, if you suffer from strangulation or problems to breathe.
A high amount of adrenaline will temporarily disable most drug-related aspects, including caffeine, alcohol, light opiates, weed (you'll still see double with some misfortune) and so on.
Don't ask me where I know that from. No, not from drug intoxication in most cases, except if you see failures of internal body functions a "drug".
Only exception would be if you actually could breathe but the "air" was not "air", but something which replaced it, by a higher voluminous mass as example. And didn't trigger warn sensors of the body.
In terms of water: if it gets into your breathing ways or even lung you'll wake up and cough like hell, together with the feeling to die from suffocation (even if you don't die that quickly from water in the lungs, some other substances are more deadly, petroleum as example..).
