Everyone always says that about alcohol. As a type 1 diabetic, I can tell you that unflavored hard alcohol has no real effect on raising blood sugar. In fact, Bacardi used to advertise Bacardi/Diet Coke as being a zero carb drink. Most red/white wine also has a negligible effect. Beer, on the other hand, is basically liquid bread. I rarely get drunk on beer because of the amount of insulin required to cover all of the carbs.
