There are all kinds of progressions from my experience here.
There are those who never drank normally - like me - I always drank to get wasted.
There'd be a lot of those drinkers in AA cos the BB view on alcoholism supports that idea.
There's also a lot of people I see here, and who are in AA, who look back to a time when they were normal drinkers.
I don't believe one kind is any worse or any better than any other...the inevitable outcome is the same.
