Okay so it sounds like what it actually does is convert the iron in your blood from Fe2 to Fe3, and that prevents oxygen from binding to the iron or something so you basically suffocate. Doesn't sound like a particularly painless way to go.
I'm not sure that's accurate (but I haven't researched). The suffocation response is induced by increased CO2 levels in the blood, not really by a lack of oxygen. Hypoxia from altitude or breathing Helium are relatively pleasant ways to go from my understanding. It seems like this would be similar to breathing pure helium but like I said I've done 0 research.

Yeah suffocating to death while still breathing sounds like a living nightmare

Yeah your body doesn't have the ability to detect oxygen levels, your breathing response is regulated by detecting co2 instead
