For a youngster like yourself, I suggest you look at it like the following. When i first got into fitness, I thought that I could never ever have one beer or alcoholic beverage. I did know in the back of my mind that one or two alcoholic beverages would not evenmake a noticeable difference in my health, performance, or physique but I was just so overly disciplined and stoic with the fitness lifestyle. The same thing happened to me with staying out with friends late at bars and clubs. Needless to say, this left me with very little fun and quite a few friends and women who thought I was the biggest tight-ass to hang with. Now, my view has changed a bit. Sure, if you ABUSE alcohol, eat junk everyday, and party until 6 AM on weekends consistently, you will encounter problems with your fitness and health goals. Now, I do have that one beer or alcoholic drink. I do have that night where I stay out until 2 AM (not 5 or 6 AM). I also became more loose with my cheat meals as well. If I have had a cheat meal during a current week and all of the sudden I find myself at someone's house or a party or whatever and they are serving junk food, I DO have it! If I miss A meal during the week because I slept late on the weekend, I do not pay mind to it. I am a hell of a lot stronger now, feel better and happier, and am more suitable to actually appearing as a tightass to a date or a friend. So, in closing, have some FUN but do not go overboard. Say A drink or TWO, tops, when you go out, and do not be a tightass with life simply because you are involved in PL.
