Diet Power calls you a "drinker" if you check the box on the Personal Information Form that says, "I drink alcoholic beverages." You are asked to check this statement only if you average more than two drinks per week. (Hence, if an average week sees you taking only one drink on Friday night and another on Saturday, Diet Power deems you a non-drinker. This does not mean that it's safe for an alcoholic to have two drinks a week, however¾the threshold is meant only for nutritional categorization.) A "drink" is defined as 3/4 fluid ounce of pure alcohol¾about what you'd get from a 12-ounce beer, a 6-ounce glass of wine, or a 1-1/2-ounce shot of liquor.
