I want to warn anyone thinking of trying this: don’t.

Obviously there’s the don’t commit suicide part, and that’s the most important part. But also, as someone who has unfortunately spent time considering various methods, I can tell you: don’t even consider doing it this way.

Genuinely sorry to be contradictive, but you absolutely would have been in a painful situation if you’d continued. The only explanation is that you didn’t get to the point that your body 100% takes over from you and forces a desperate, painful, writhing attempt to get air.

You would die of increased CO2 concentration in your blood long before you actually ran out of oxygen. That increased CO2 would be very painful. Like, lizard brain stem absolutely taking over, full panicking levels of painful. Don’t try it!
