We all know SN is a poison to our bodies causing methemoglobinemia and hypoxia/anoxia. Therefore, it should be understood that the outcome will vary amongst individuals depending on a myriad of factors which I will not go into details about now. SN was never an "almost certain death" and just a possible means to an end. When you mention having "doubt all of a sudden", it shows you haven't researched this avenue enough. People express doubt for numerous reasons and rightfully should, especially when several users on this forum state they failed their attempt by using SN. Nobody wants to fail, but the fact remains that everyone's body and situations are unique. Sharing doubts is a way to communicate about how people feel about using a particular method and if it's the best method for them. This is what is called "critical thinking".
People should be concerned about adverse outcomes of using SN (in this case) because it isn't foolproof. H
ypoxia can cause a myocardial infarction, stroke (with subsequent brain damage), blindness, convulsions and many other serious bodily injuries. We read or hear of the ppeh stating it's "reliability is a 7 out of 10" but there really isn't any evidence in the book to back up this claim. What if you are old and frail with several medical comorbidities versus being young and very healthy? On this forum, we just read "goodbye" threads of people who took SN and if we don't hear back from them or they ban themselves, we tend to believe they were "successful". There aren't too many published cases out there because not too many people actually choose this method but, instead, use more lethal means such as a gun or hanging (use of a gun can even fail). Those cases tend to get more sensationalized by the media. Unless you have access to various scientific medical journals (especially forensics), most will not find the actual cases of attempted or completed suicides by SN. So, we search on the Internet, read what we find and then comment on it. As someone mentioned above, cases may not be leaked or told to the media because it could cause "copycat" suicides, especially with the ease of attainment of SN in most countries.
I am not advocating for anyone to use this method or not (or any other method for that matter). I'm definitely not fear mongering. I feel SS has given people a chance to share ideas, learn, address concerns, find hope, etc. In the end, each person must choose what they believe is best for them.
BTW, I'm not attacking you but trying to make a point that SN isn't the miracle agent for a
quick and painless death. It may be for some, but not for others.
