One of the best things about quitting when I did was that my kids were 6 and 8, five years later they don't have any memory of me as a drinker.
I remember one day, a couple of months before I quit I was suffering through a "slow roller hangover" at the drag strip. I was driving my sweet 10 second Max Wedge Plymouth, it was running like a top, the kind of thing that I generally live for but I just wanted to put it back in the trailer so I could finally get my drink on and feel some relief. That was a true "moment of clarity".
