http://www.alcoholics-anonymous.org/....cfm?PageID=71 Be honest and true to yourself. Only you can decide for sure.
I felt I was a high-functioning alcoholic. Never had work problems, had a nice home, beautiful wife and kids, friends and family. It's still a little shocking to think about how quickly I turned the corner and my world turned upside-down. Divorced, living in a little apartment, joint custody of our children, and daily AA meetings. No regrets, I have an awesome life, and a strong awareness that I'm an alcoholic and can never safely take a drink again.
