Method The problem of violence and suffering

[Stadsjaap]

Hi.
In considering the myriad proposed ways to CTB, something has come to my attention: When it comes to end-of-life care, it oftentimes boils down to a choice between faster methods, usually involving some sort of violence (defenestration, drowning, crushing, MVAs and so on) and less violent methods, but which tend to involve more or longer suffering (poisoning, hanging, intentional drowning etc.)
The problem is that most of us are not inherently violent people; nor are most of us inherently stoic enough to seek a slow, agonizing death.
Which brings us to inert gas asphyxiation. Which, to me, looks like the Rolls-Royce of methods, short of the Pegasos Clinic.
Has anyone had any experience with people choosing this method? Or god forbid, who attempted it and somehow managed to fail?

It's extremely easy to fail this method.
First, survival instinct, once you started there's a way back.
Second, if during your attempt, the gas, i.e helium makes you fall or whatever, for example the tube you inhale from breaks... you just need to fall and your system can let fresh air in, and you're fucked. Prolonged exposure can leave you paralyzed for life.

But it's the Rolls-Royce indeed, it's just hard in practice because of those two reasons. With helium, you just lose consciousness without it hurting you. You just pass out peacefully and die.
