I still don't agree that those few beers made any difference to the enjoyment of the holiday with your family, I think your addiction is calling a lot of the shots Golfdad by selling a few fairytales as to why alcohol is needed, Sober you would have had just as good a time.
For me having a few wasn't a validation that I had control, I could probably have a few today and leave things at that, however not on Day 1 but over the course of a week or so things would escalate back to as bad as ever, the false sense of security would be very shortly lived.
Great to hear you're sticking around!!
