One of the chilling things about that post by the young man who died is how much time and energy he had spent thinking about drinking and alcohol - to the point that he claimed certainty and confidence. Focusing a lot on alcohol can be an indication of a problem, as it speaks to a kind of obsessive behavior that can accompany addiction. I do not say that to criticize him but rather to note it for those who may encounter it in someone with a suspected drinking problem.
