IN MY EXPERIENCE, there are two parts to my mind; the rational human part and the addictive voice, which only cares about pleasure, no matter the cost or consequence.
No matter how wonderful it sounds to be able to control my drinking, it's just not possible. Why?
Because that first drink is a double whammy! It paralyzes the rational human part of my brain, which is the part that could possibly stop me after a couple, and it basically throws a meatball to the animal addictive voice part of my brain.
End result is a paralyzed rational mind with all inhibitions anesthetized and a pleasure seeking addictive mind that's all fueled up like a Tasmanian Devil. In a situation like that, there is no telling WHAT might happen.
I might have two drinks and quit, or I might have 22 drinks and end up killing myself or someone else. There's no way to tell once I've given up control of my rational mind.
It's the very first drink that's the most dangerous. The only way to truly win is not to play!
