I don't know if this is what you would call a psychic change or not but I can describe 2 experiences. The first is the first time I went to AA voluntarily. That was when they read the steps and I broke down because not even 1% of me could deny any more that I was truly powerless over alcohol. The crumbling of the walls of denial was big for me. The second is my letting go, turning my will over to God and seeing his will work in my life. Not only lifting the drink obsession but freeing me from the bondage of self. These are my experiences only so far.
