Moi, 3.5 yrs ago.
I have written about once or twice here somewhere. Spent a week in a coma after and the psychological fallout from a "failed" attempt is probably the most difficult thing to overcome. I am already disabled and have cerebral ataxia, so could not really do much more damage in that respect. The left side of my body basically doesn't work anymore.
I took my cocktail of Ami, codeine and propranalol , sat down with my music on and that was that. I died somewhere around 6 hours later. A neighbour did the CPR thing until medics arrived. Docs told me another 20-30 mins I would have been brain dead.
The only lasting impression is complete darkness, but with a slight shimmer to it. I was floating in nothingness, blind, but could sense being a part of something huge. Like everything was connected somehow. I was definitely at peace. It is the most seductive sensation i have ever known and is the sole reason I no longer fear death.
There is the chance that all of it was my mind coming to terms with death, or it could all be my imagination. How do you rationalise something like that? I have given up trying to understand the inexplicable.
