Coming from a BS artist as yourself, that is a compliment. As far as the "evidence" you demanded (not that I need to justify myself to the likes of you) it comes from working with other addicts and alcoholics and talking to therapists and rehab conselours. And I think they know just a little bit more about it than you do. How many old junkies do you know vs alcoholics?
Keep slinging the BS pal - I am another one who does not buy it.
