how likely is sn failure?

Okay, John. You win. Have a good day.

As I said in the other thread:
All case studies are only examples that report on the time period from taking the SN to leaving the clinic. We do not know how the persons are
doing after 1 week, after 1 year or today. How are they mentally, how are their kidneys and liver? Also, many people do not realize that they have mental health problems. We will not know how those people are doing today.

And there is another risk. The PPH recommends taking an additional 500 mg of Diazepam in the latest edition. This makes the method more peaceful, but in case of failure, another problem arises. A Diazepam overdose causes brain damage as a result of respiratory depression and respiratory arrest.
So there are 2 significant risks in one method

SN kills by causing hypoxia - methemoglobin cannot use oxygen like normal hemoglobin - so SN and respiratory depression will act synergistically to increase the chances of dying.
