You're still very young yet. When I was around your age, I made several half-hearted attempts to quit and of course, none of them ever stuck. I was very "high functioning" too, with a great job, lots of social activities, etc. As the years went by, I gradually got deeper and deeper into the drinking. I never missed a day of work, but my social life started dwindling as no one could keep pace with my drinking. Anyway, after nearly 30 years of drinking, I finally ended up with the morning shakes and crippling panic attacks. That was my "bottom" and I was able to dig out before it was too late. I hope you decide to give it up before it's too late. I wish you well.
