I have a gin and tonic every night before bed, am I an alcoholic?

How big is glass. One drink of spirits such as gin would be 1.5 oz. If this is all very unlikely you would have alcoholism. However people with alcohol problems can be crafty. Their one gin and tonic may be out of a 24oz tumbler. But they can gladly tell everyone. "i just have one drink per night" hope that helps. Not to be cynical but it does happen.
Miss one night. Do you feel sick if you do not have a gin and a tonic at night?
