It might not be an addiction, per se, but an allergy. My world renowned ENT allergist told me that you either crave or abhor what you are allergic to.... the thing with an allergy though is once you go off it for at least 3 days up to 10 days... you feel better and don't physically crave it. IF you do that, and still want to prove it's an allergy, then take a day and drink a bunch of it and if you're sick or craving again...it's an allergy.
Wanting something and doing anything to get it is probably a good difference between wanting and addiction.
