How to kill myself with nitrogen

[Prime0]

So I made my researches apparently this is the best way out, buy an oxygen mask, hook it on a nitrogen tank, put on the mask and turn on the tank, depending on the person, you will pass out in a minute or two and die in a maximum of 10 minutes.
There's supposed to be no CO2, but probably our body throws it away when we inhale the nitrogen by using a mask, right?

Let's come to my main question, the technical part of this job is the problem, does the pressure of the nitrogen cylinder I buy and other things matter? Also how do I put the breathable mask to the cylinder? Wouldn't a non rebreathing mask be better since it has a filter? Does it have to be 100% pure? Wouldn't 99,998% purety be enough? I live in France, as site where I can order it digitally for now I've only found vogelmann, would this cylinder be good? I don't want to mess up the technical part so I would be happy if you give me the spesific details or if possible even the links of the spesific cylinder and mask that I should use.

Cylinder is OK and purity is OK.

Cylinder is OK and purity is OK.

And what about the pressure? Is it okay? Also as far as I know, isn't nitrogen gas cold therefore dangerous to inhale it?

Check The inert Gas Exit Bag Mega Thread, specifically GasMonkey---The mask is attached to the flowmeter/regulator via clear plastic tubing, which in turn is connected to the Nitrogen tank

Actually I remember ordering a CO2 tank Years ago and it was cancelled last minute…. I would want to complete my ctb in my sleep I know that's how this Korean singer completed his in 2017
