Dee's advice on "urge surfing" was really helpful. For drinking as well as many things really - becoming aware of your thoughts, seeing them as separate from yourself, not acting on them right away - it's advice that most people I know could use in lots of areas of their lives.
Also "playing the tape through" - going down the line of what it is to take drink, get drunk, suffer and be back in the panic-striken uglies of that shame-filled life - seeing that tape play out makes it so that starting to drink again is not attractive anymore.
