Hmm well only you can decide if you're an alcoholic or not.
If you can spare ten dollars , have a read of
Amazon.com: Seven Weeks to Sobriety: The Proven Program to Fight Alcoholism through Nutrition (9780449002599): Joan Mathews Larson: Books and you might find some of us alcoholics did that when we were early into the progression.
For another small amount read Under the Influence and Beyond the Influence for more descriptions of stages and adaptations that happen
Amazon.com: Under the Influence: A Guide to the Myths and Realities of Alcoholism (9780553274875): James Robert Milam, Katherine Ketcham: Books
The books are probably a lot less than you spend a week on drinking and a good read IMHO
Whether you're an alcoholic or not , that's a lot of units to throw at your body and something will probably give , given time.
