if i ever drank it would only be to the buzz, after that I would stop. My parents would probably make my life a living hell for a couple weeks, but it would blow over after that.
Your family will always be behind you, and regardless of what you've done, things will get better. I'd advise you to just be careful with whatever you choose to do in life, and be responsible. Thankfully, you didn't choose to make the mistake that many do, when they take a drive after a couple drinks.
