understanding addiction....

Some of the smartest people I know are addicts of one sort or another, also some of the dumbest people I know are addicts. I don't believe a weak mind has anything to do with it. It is a chemical imbalance maybe causing a craving for the offensive thing.

On the other hand I used to drink a quart of vodka per day. Basically I was a functioning alcoholic with a full time job, hobbies, and resposibilities. One day I just got tired of feeling so crappy that I quit and haven't touched any kind of alcohol in the past ten years. Did my imbalance go away? Or did I suddenly become less weak minded?
