I have to disagree.
I do think there is a difference between a one off event and a full on return to drinking.
And if semantics help people who have erred by drinking stop turning it into a life style change back to old habits, I am all for it.
Personally, like Al said, I am all or nothing so have never had a slip, but for someone who has, a little semantics can go a long way to limiting it, me thinks.
But I understand the points on the other side, just putting it out there.
