Falling off the wagon is forgivable. It makes it sound like an accident so it's a little more O.K.
If you were to substitute the words "Made a Conscious Decision to Drink" instead things are a little different. Now the ball is on your side of the net and it's up to you to decide what to do with it. I know it's difficult and I am not judging criticizing or condemning. It's not even something I am telling you. I'm giving you a new set of words to use next time the temptation arises. It's something to tell yourself. Especially when this is a program of honesty.
