Congratulations on staying sober. Hopefully your friend will give sobriety a try before it causes irreversible damage in her life. Your label / diagnosis of her behavior will not be a factor in that. Does she know you have quit? Feel free to share the benefits you have discovered and when she calls herself an alcoholic to challenge her on that. For example, "If you really think you might have a problem, there is nothing like taking a 30 day break to think about it. Think of it as a cleanse. If you want to go to a meeting, I would be happy for the company."
