understanding addiction....

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?

No, you were never weak minded to begin with as you kept your **** together when you were a functioning alcoholic and knew when enough was enough!....And, you're still living!
