Well, when I was younger, I'd really disliked the bitterness of beer, and occasionally had Shandy, that wasn't strong enough to induce any side effect. Then I joined a Sports Academy and signed a contract stating I'd never drink Alcohol, turned 18, and got sloshed a few times. It's not really that bad in moderation, although you can definitely feel it isn't doing your body any favors. You guys should feel free to do what you want, whilst always keeping in mind the potential consequences of your actions.
