Mixing pills to overdose or SN and anything that requires ingestion for a long, painful death simply for the sake of looking decent.
Firstly because of a personal phobia (emetophobia, fear of choking and fear of food poisoning)
Secondly this isn't easy to obtain and hide.
Lastly because I don't really mind looking good once dead so I really can't find any positive in this method...
My method is Train Decapitation, it's quick, reliable, free, easy to access and I think you don't look so gruesome once beheaded.
I also find it to be a funny method as im french and this reminds me of when, in history class, we were taught about guillotine methods in the past. It always fascinated me and left me wondering if it's true that you are still conscious for a few seconds. I guess I'll find out but I will not be able to let you guys know...
