Wow, that is a super hard choice. Would I rather take 10-20 minutes of tachycardia and vomiting, followed by unconsciousness and death? Or would I rather chemically burn my whole GI tract, while dealing with hours of diarrhea, vomiting, CNS depression, low BP, and drooling (over production of saliva is the body's response to burns in the throat)?
SN is recommended for a reason. Don't ingest random chemicals and expect a peaceful end.
