I'll give my own two cents on this and a lot of people disagree...and that's fine. I've said many many times about not letting your lifestyle interfere with loving life and I stand behind that 100%. I go out and have a few beers about once a,month socially, and I don't see a fucking thing wrong with that. I do it on cycle and off and it has never once hurt progress. You just have to know and practice moderation. You do more than that, and its your own fault when you spin your wheels. I was at a wedding and reception yesterday where I did consume quite a bit of alcohol. I had a great time, which is what life is about. Just don't get carried away.
