I used to practically beg myself not to stop at the liquor store on the way home from work. I would say to myself "please can we just not this tonight." I always stopped and got a pint. There was something in my mind, not even a craving, but I felt like I had to. It was just what I did.
Then something in my mind switched and I realized I did not have to drink. If I wanted to I could escape. So I did.
