NaNO2 is NS?

[whoever]

Hello again.
I am sorry for my ignorance but there are concepts that I do not understand well.
A member of this forum has suggested using sodium nitrite. Is it the same as NaNO2?
Is it a food preservative?
NaNO2 is NS?
Can someone explain to me how many grams I need to mix with water and how much water?
My weight is 130 kilograms (I am very large). How many grams do I need for my body and with what amount of water do I have to mix it?
And finally: Is it painful?
Thank you.

Read through the posts concerning SN. Your questions have been asked many times before. Yes, SN is a food preservative and not the healthiest by all means but still legal to use.

I concur, and lest anyone feel daunted by the length of the megathread: The basics are explained on the first couple of pages.
