What kind of pills is Arthur taking ???
Is he taking his wife's Painkillers. Taking just any medication isn't a sure fire or peaceful death. Aspirin can be the most painful because you usually get sick but the after affects kill you. Certain tranquilizers or things like Xanax may put you to sleep unless you swallow the entire bottle at once. The only thing that sounds remotely peaceful is strong Opiate painkillers which will slowly just stop you breathing.
Was just wondering what he may have been trying to off himself with since there was a very macabre plot to the film ?
THERES NO ROOM IN MY CIRCUS TENT FOR YOU !!!!
