Here is what my alcoholic mind does with such experiences.
As a watcher - You got away with it, maybe I can too. People are always telling me about the fatal first drink yet there you stand unscathed. Maybe they are exagerating.
As a relapser: Wow, how did that happen? Glad not much harm came from it. Back on the road now. Then, after a few days or weeks, "it's interesting that I didn't lose control. Maybe I am not alcoholic after all. Perhaps the break from drinking was all that was needed to set me right again." Then perhaps later still, the thought comes that a drink would be nice. I have been sober a long time without any problem, and last time seemed to work out ok....
You get where this is going. The big problem for me was I never saw the first drink coming. Alcoholism can be very subtle. In hind sight I could see all sorts of things, but I never could recognise the danger signs in advance.
