This is a loaded question, as the respondents don't intend suicide, so are not in the frame of mind they would be in a suicide situation. In a lucid moment I would, of course, choose the most peaceful method available, but if I was suicidal I probably would feel all the negative emotions, such as anger, despair, fear, etc. In this frame of mind the natural inclination to lash out would be turned inwards and result in violence to myself. In fact I'd probably end up getting hold of a gun and blowing my brains out. It is also probable that I'd write an extremely vitriolic letter before doing this.
