I didn't say that you should get rid of all the drinks in the house. My own house has loads of drink in it because my partner is not an alcoholic and nor are most of our visitors.
i said that YOU should not keep drinks in the house. In other words, get rid of any drinks "with your name on." When you say that you keep a can in the fridge, presumably that's a can that you feel entitled to drink? My advice would be to get it straight in your head now that there are no drinks in the house that are okay for you to drink.
And, yes, I agree - getting a massive teapot would be a step in the right direction. But in your post you seemed to be laughing it off as a ridiculous idea. It's actually an excellent idea, easily achievable, just as easy, and certainly wiser, than buying lager or wine.
Your main enemy in this whole process is going to be your mind trying to convince you that somehow alcohol is a special case; that you somehow need alcohol in a way that you don't need other things you like (crisps, for example, or Bourbons); that drink is an essential part of life (it isn't - millions of people regularly go without it, with no ill effects); that drink is so necessary to human existence that it justifies extra sacrifices (so getting up to get a can of Coke or pour a cup of tea is a lot of messing about, but getting up to get a can of lager or pour a glass of wine is no trouble at all).
When you ask yourself WHY a drink with alcohol in it is different from a drink without alcohol in it in practical terms (answer - it isn't) you start to uncover the real problem, which is a peculiar and illogical relationship with alcohol wihch most of us have found to spring, not from informed and sensible decisions, but from a real and unhealthy dependency.
Hope this makes more sense.
