It’s been almost twelve years since I took a drink, and I’m still struck by disbelief when I see someone in a restaurant with a half-finished glass of wine near at hand. I want to get up, go over, and yell “Finish that! Why don’t you finish that?” into his or her face. I found the idea of social drinking ludicrous—if you didn’t want to get drunk, why not just have a Coke?
