I am casting a large net and I think I am going to catch the Leviathan known as Joel! Harpoons ready; check!
The site that Joel is posting about Alcohol http://www2.potsdam.edu/hansondj/AlcoholAndHealth.html is written and maintained by David J Hanson P.H.d. This site is funded by the Distilled Spirits Council of the United States. The Distilled Spirits Council of the United States is an alcohol lobbying association. I will leave it to all of you make your own decision on David's research.
From my experience, dropping alcohol for 30 days coinciding with the paleo challenge, I felt very good. All weekend I was productive and not focus on sitting in front of the TV while drinking, or sitting in front of the TV nursing a hang over and feeling sorry for myself. I highly recommend it.
