I don't think this is the answer that you want to hear, but I believe alcoholics stay into deep denial, until they don't. I am jaw droppingly dumbfounded at the number of times my very alcoholic mother will speak of someone else's alcoholism with disdain in her voice. She and my dad have basically isolated themselves from all of their siblings, yet they do not see that the common denominator is themselves. My AM was basically telling me the other day that a close family friend who she recently visited is not portraying her life to be the way it really is in real life. HUH?!?!? Really?!?!? Doesn't it take one to know one?? Honestly, in a detached way, I find alcoholics' denial one of the most fascinating phenomenon I have ever encountered.
