The "I'll drink tomorrow" routine never worked for me, either.
I made a decision that I quit for good -- even if it killed me, and I was sure that it would kill me within a few days of not drinking.
But, I was more serious about it the last time than I had ever been. The reason was: I knew drinking was going to kill me. And, I knew, (in the condition I was in) that not drinking was going to kill me. So, I figured, either way -- I'm going to die. And, at least my kids would have been able to say "One thing about it -- he died sober."
Much to my surprise... a few years later, while studying the Big Book, I came across two different places in the recovery section of the book, that the question was to be asked of the new prospect: "Do you want to quit for good?" And, "Do you want to quit forever?"
Other than myself -- I can only think of two others that brought those two questions up in the Book, and they were my Big Book sponsors.
After reading the BB & Dr. Bob's story, and especially Chapter 7, "Working with others" ... I can only imagine the reaction of Bill & Dr. Bob, if they asked a new prospect: "Do you want to quit?" and the new prospect said... "Yes. But, only for 24 hours."
They wouldn't have wasted their time with him. They would have let him go and went looking for the one that wanted to quit for good -- and forever.
I can understand the psychology, when trying to help someone get their first 24 hrs, of trying to help them get 24 hrs. Or, the next hour, or the next minute, or the next heartbeat. But, that isn't going to work for the long-haul -- for an alcoholic of my type.
Looking at the 10th Step in the 12 & 12, Bill indicates that the First Nine Steps -- PREPARES us for living the One Day At A Time Program, so that we can maintain our sobriety through fair weather and foul.
If we're trying to stay sober one day at a time, or even live one day at a time -- WITHOUT taking those first nine Steps -- we're going to be pretty miserable and unhappy campers -- during most of those "One Days".
I think we also need to be aware that not everyone in AA is an alcoholic. There are some, who were "problem drinkers." They drank like an alcoholic but they weren't alcoholic. Given a sufficient enough reason they could just quit and never go back to it.
For those of us that are alcoholic -- no matter how great the reason and no matter how great the desire -- we ALWAYS went back to it.
By taking the 12 Steps, we recover. We get restored to sanity. The alcoholic insanity and the emotional compulsion to drink gets removed. And, then, we are given the power to help others. That same power that we are given to help others -- keeps us sober -- while we continue to help others to recover.
