A good friend quit drinking on his own when he realized he wasn't remembering blocks of time from the night before. I've been spared overdoing drink by my body chemistry. I enjoy a wine or beer with meals, and the celebratory bourbon now and then, but otherwise it fails to make me cheerful, talkative or happy. I do not feel entertained or "smarter" or otherwise invigorated. The primary effect is a sort of slow sedation that leads to not very good sleep. In the process of that, I only get more quiet, so I'm not a party animal unless the party is pretty sedate. I am not Asian, but I think I may share with some Asians the trait of poor alcohol metabolism. My parents were gin martini lovers, but they raised some hell while properly anesthetized, which wasn't always great for their progeny. But they never missed breakfast, or fixing it for us, or jobs or family occasions, so they did well with it in that respect.
