Sorry let me clarify.
This is actually my fifth attempt. The ones before this one were drug overdoses both with exit bags, drowning and water intoxication.
What I mean by "scientifically" is I read case studies, medical journals and news reports from a tonne of different online sources. I also read something called Final Exit and of course PpeH.
But I am by no means not even close to an expert.
Judging by my 6 failed attempts I would and should not even be considered anything but an incompetent failure obviously.
I also have had at least a dozen instances where I was going to go through with it but never did.
The 6 I mention are ones where I actually attempted.
I am in my late thirties.
