If I had the option of a method as peaceful as Nembutal which means that I can die just like falling into an eternal sleep, then there would be no need to delay the inevitable. I view a peaceful suicide that happens without pain and struggle as being preferable to everything else as such a thing would solve every problem and prevent all future torment.
Death truly is the only relief in such a dreadful existence, and anyway we are only just waiting around to die, we are just slowly dying waiting for death to take us away. So of course the best way to cease existing would be peacefully on our own terms, I don't see the point or appeal to existing anyway, such a thing just leads to unnecessary suffering. The only thing that appeals to me is everything being forgotten about in death.
