LK, if you read the Alcoholic A book there is a case about a guy whom realised he loved to drink but he realised early that it would ruin him and he would not have a career. So he made an agreement with himself that in his mid 50's when he had made himself successful that he would take up drinking again. He did and was dead 2 years later. Make sense? No but it was a bit of what I was talking about.
You do realize that that guy is a huge exception to how things usually play out. People who are prone to addictions generally do not have that kind of willpower. As for White, if he did in fact have a substance issue, it likely started long before he signed any substantial contracts, and, well, if you've ever known anyone with an addiction, you'd know that having earning potential like that is hardly a reason for them to stop. In fact, it's usually the reason they go harder.
