If, in retrospect, you think that having a chapter to finish was a good reason for drinking, and that doing so helped you in a tangible way with the chapter, and most of all that you have not suffered unduly as a result, then I am more than happy to agree to disagree.
However, as I say, I used to make excuses like this all the time - and, in my case, they were, without exception, lame. All they did was allow me to drink, and all that did was make me unhappy.
I am sorry if you do not find my experience helpful. I am sure someone else more helpful will be along soon.
