For people interested in symptoms with SN ingestion. Full text cases (except one) only. Not known the SN dosage in almost all cases.
Hope the recommended peaceful dosage(s) shut(s) down our consciousness rapidly and shortcut(s) the several painful symptoms.

Accidental poisoning of two laboratory technologists with sodium nitrite.

Case one: A 21 -year-old woman was in good health until 30 mm after eating her breakfast in the hematology laboratory of an adjoining pediatric hospital, when she noted the onset of symptoms, which she described as a throbbing roaring sound in her ears. She started work but had to stop because of threatening syncope. She also noticed rapid and strong palpitations as well as a generalized tingling sensation. She induced herself to vomit and presented herself at the Barnes Hospital emergency room. Upon examination, she was noted to have marked cyanosis of the fingertips, lips, and face. A presumptive diagnosis of methemoglobinemia was reinforced when a sample of her blood remained chocolate-brown when ex- posed to air.
Case two: This 34-year-old woman was a co-worker of the other patient. In good health until shortly after eating breakfast in the same laboratory with her, she began to feel weak with diaphoresis and nausea. She also noticed numbness and tingling in her arms and legs. At the Barnes Hospital emergency room, she was found to be short of breath, tachycardic (130 beats/mm), and cyanotic in the arms, legs, lips, and face.
Outbreak of Sodium Nitrite Poisoning
Am J Public Health Nations Health. 1945 Nov; 35(11): 1217–1220.
Morris Greenberg, William B. Birnkrant, and Joseph J. Schiftner
In each instance illness occurred within 5 to 30 minutes after eating breakfast in a cafeteria on Chatham Square. All were between 60 and 80 years of age and all were of the derelict type, living in cheap rooming houses on the Bowery. Seven of those ill lived in the same rooming house; the other four lived in different rooming houses of the same type, and were unacquainted with each other. The clinical picture was similar in all. Within 5 to 30 minutes after breakfast, the involved individuals became dizzy, felt weak, and complained of abdominal cramps. Eight of them vomited and all had diarrhea. Five of them became unconscious shortly after onset of symptoms.
