Alright i know this may be a bizzare post... but i need help to finish a short story i am writing. My main character kills himself using some sort of or chemical or supplament that is readily available to a teenager. And it has to be certain that it would kill him. He is a medical genious, and ive been able to avoid showing his factual knowledge up untill now, but now i need somthing that would be a sure thing ot kill him. Is possible... painlessly... becasue if he chose to do somthign that would hurt himself (in terms of pain) then it wouldnt go with the story....anyway... any help would be awesome.. thanks
