Great writeup. As someone who never drinks, and never has, it continues to sound like a drug to me and I want no part of it. That said, I still get questioned about my decision like I have 2 heads.
I started drinking (about once a week) two years ago.
It's moderately nice from time to time, but I also think the decision to avoid it for twenty years of adulthood was a good one - I established who I am and what my coping mechanisms are for stress, and now it's a nice little social adjunct.
My advice: if you're even the least bit undecided about drinking, don't do it. You can always give it a shot later. Or perhaps you'll never drink; that's great too.
