You're right, drinking seems to be promoted almost everywhere you go. You're still young with quite a future ahead of you. So seriously ask yourself, "How do I want my future to look like? Do I want to live with a bunch of regret?" And, if you keep drinking, you will keep stacking up regret after regret after regret. One thing that has helped me is to surround myself with non drinkers. It's not as hard as it might seem. I've always been into health/fitness and I find that many of those types don't drink either. And, further more, they won't likely pressure you into drinking because they will understand you are trying to be as healthy as possible like they are. So, if you're not already into fitness, I'd encourage you to start.
