Someone said "you're overthinking this". That's true. The beast(I refuse to capitalize the label) is nothing but an incessant desire for pleasure in any form including destructive form. Don't personalize it, don't name it, don't personify it, don't give it prominence, don't give it power. Deny the destructive impulses it produces. In the case of alcohol, it's as simple as: "No, I don't drink".
