KRob,
Welcome to SR. I was in the same type situation, couldn't stop at 1 or 2. There are no "petty" issues when it comes to alchohol abuse.
You are smart enough to realize at such a young age what alchohol can do to you and should be proud of the fact that you recognize this.
Keep coming back here and posting, SR is open 24/7.
Focus on healthy and fun
