I'm sure some of biking culture can knock a borderline alcoholic over the edge but I'm not certain its as serious as this article is trying to make it seem. I've done a number of MTB, Cross and Road races that were accompanied by beer or hard cider and I see nothing wrong with knocking back a drink in that case but a person can be moderate and still enjoy themselves. Since I usually am the one driving I also limit it to the one and have never had more than that after a ride or race. If you're finishing a ride and waking up the next morning with a hangover you need to get your life together. Most people I know stopped having hangovers by the end of college. Will say that maybe it was the crowds I moved among but we had a much bigger munchie issue, still do at times.
