Its a very interesting subject. I had an experience which prompted me to ponder the same type of question: A couple of months ago, I decided to stop all caffiene with the exception on one cup of half-caf coffee in the morning. I got through the withdraws (headaches) and did OK for a couple of weeks. Then I decided to have a soda one afternoon. Then another the next day. Before I knew it I was consuming MORE than I was before I quit. It made me think that the same scenario would probably play out if I ever tried to drink alcohol again. Is there any correlation? Maybe not, but it raises some interesting questions.
