Yep. That's the line I'm trying to identify more clearly. Seems that the current criteria are pretty fuzzy.
Of course the criteria is fuzzy. They is no set in stone millimeter you cross over can be mutually agreed upon.
I'll tell you right now honey, you are not a heavy drinker, and don't have a problem.
For purposes of this thread, instead of using terms like alcoholic, heavy drinker, binge drinker, etc. I'm just going to use the words "problem drinker"
If it causes problems in your life, regardless of whether you personally think it does, then there is almost definately a problem.
From what you say, you don't appear to have one.
For those regular people out there who say "I just don't understand how...." Well of course you don't understand.
Same as for people who say "I just don't understand how....you don't believe in God, you don't want children, you don't like (fill in the blank), you don't want to get married, you're gay, etc.
That not understanding goes from one extreme of having no interest in understanding, to the other extreme of really having made the huge effort and research, and it still eludes you.
Not saying you can't make a very good educated guess/decision about something, but it's not an exact science.
