Harder to get but you have to look for oxidizing agents that does the same as SN like benzocaine and lidocaine.
All those cause methemoglobinemia but for benzocaine and lidocaine there have been only a handful of cause that led to death either accidentally or on purpose.
I think know , i could go for benzocaine or lidocaine , you don't need all kind of meds and regimen like SN.
Chubbyemu posted a video a while ago that explains the case of someone drinking numbing spray containing benzocaine which acts similar to sodium nitrite. I recommend watching the video as it explains the effects, the chemistry behind it, and even gives alternatives at 12:52 lol. video
