Good for you for not drinking.
I know someone who tells the story of being sober for several years, and driving home one day. Somehow, for reasons he's not sure of, he passes a convenience store, and turns in and buys a bottle of Jack Daniels. He then cracks it open in his car, and has it between his legs, drinking from it, as he drives the last 3 miles home.
The whole event took less than 15 minutes. It resulted in a 2 month bender that ended in a treatment center. Scary stuff!
