I don't understand why people think it's so good to go x number of years without an alcoholic drink . If you had to stop it was because you HAD to, not because you wanted to . Presumably because you couldn't control yourself.
I will point out I'm using the word you as a generalisation not directly at someone.
If you have the will power to leave something that you can't control then we'll done. But it's nothing to celebrate is it Shirley?
