I used to have one homebrew a day but took a three month break with no beer when training for a marathon. It was quite eye opening seeing how better I felt in the mornings. After the marathon I have been having one or two beers per week at night and I can definitely feel the effect in the morning. Taking a clean break re-calibrates your body to what life is like without alcohol. I then read a few articles on the carcinogenic effect of alcohol. Basically it seems that there is no safe level of alcohol as a carcinogen.

I still drink beer but am sure that it is not good for me so keep it in low quantities.
Was the realization that you weren't going to feel any better than when you woke up depressing?
