Google the following: "ego alcoholism"
I am much more than my ego. Part of my spiritual path is delving into "Am I really more than my thoughts, body, actions" - stuff that is probably best left off this board, but it dovetails sobriety beautifully.
If anyone is interested, look up the writings of J Krishnamurti, Eckhart Tolle, OSHO, you will start to see the part the 'ego' really plays in our lives. Heck, pick up Frannie and Zooey and give it a read (Salinger), it's more entertaining.
As related to alcoholism - Dr Harry Tiebout's article on the mechanism of ego on alcoholics remains the best I have read to date.
The part that the Freudian ego plays in alcoholism is extrememly useful in my experience...we may have to disagree on that dee.
