This is a sign that you may be an alcoholic. One drink sets off a craving that can't be satisfied with a drink or two. It is a progressive disease that leads to continued drinking despite negative consequences.
I know how hard it can be, because I am a recovering alcoholic and drug addict.
Call AA if you think you have a problem. They're in the phonebook, or online at
