The Big Book gives us two alternatives to face if we are an alcoholic of the type to which the 1st step applies.
1. Go on to the bitter end, blotting out the conciousness of our intolerable situation the best we can.
or
2. Accept spiritual help
In another spot it gives us the same alterantives in different terms
1. To be doomed to an alcoholic death
or
2. Live on a spiritual basis
So, I would say if you believe that the 1st step is true for you and you are not fond of the idea of dying an alcoholic death, you've got yourself a good reason to quit.
Bottom line of the first step- I will drink no matter what unless I get help. And for an alcoholic of my type, to drink is to die.
Hope you get some clarity here on SR. Best wishes to you.
