The further a binge drinker is away from his last drink, the closer he is to the next. And it is pretty much fact that the active alcoholic will pick up at the most inappropriate moment. You can guarantee that the next drink is well and truly on the horizon, the obsession does not care about work load, or the effect on other people.
I could see your decision was already made in your first post. Fine, it's your life and your decision. This thread might be an example to others that, if the obsession has already come back, no amount of good advice, strategy, or clever tactics will penetrate with sufficient force to keep you safe.
Now I wait and see and pray that I am wrong.
