I am not a great fan of separating people into alcoholics and non-alcoholics. I have seen it used too many times to justify drinking. I am of the opinion that EVENTUALLY everyone will lose control of their alcohol consumption and the addiction will get the upper hand. It's just that with some people they slide down the trap quicker and we tend to call those folks alcoholics, but everyone who picks up a drink has fallen into the trap,IMHO. So no, I don't believe there is any such thing as moderation with any addictive substances, including alcohol.
