Lot of people including myself don't realize that we drink because of the Effect produced by Alcohol consumption. Once we cross the line, we no longer can live without that effect. If we force ourselves, we become restless, irritable and discontented, unless we experience that sense of ease and comfort that we get drinking a glass or two. But we also have a physical condition, some call it the allergy, that will force us into drinking more than what we originally planned.
