I'm maybe far too rigid and unforgiving, but
i was intoxicated enough to hardly be thinking more then a few seconds ahead. And to ensure this NEVER happens again, i have given up drinking.
sounds more to me like he might make it through to Friday night without drinking again, but that's it! IMO, the only safe answer to turn his life around is to swear 'not again!'. If you get yourself in that state, you are addicted. Sad to say, it will not last a week. I don't think he has the resolve. Out of sympathy for himself, he will pour more of that poison down his throat. I've heard it too much, seen it too often. Cold Turkey is the only answer when you have behaved like an arse like this.
