In his book On Writing, Stephen King confesses suffering from an alcohol addiction that nearly destroyed him. Thanks to a family intervention, though, he overcame it. Reflecting on the experience, King writes:
"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?"
