Well said BP,
I was sober over 5 years when I drank again, the last two years or so without AA, just me.
I drank for another 14 years before I surrendered. It is AA and the steps all the way for me now.
If you are doing great and have no issues about alcohol then I commend you. However, if booze is intruding on your thoughts, calling your name from afar, becoming an issue of obsession, then you may wish to consider doing just a bit more for yourself.
Try AA for a month, you've nothing to lose...
