Passing an alcohol: Test is the very least of your problems. Alcohol is metabolized in the liver, and sweating and urinating remove only a very tiny amount. We metabolize about 1 drink per hour, so a fifth would take a day or more to completely be metabolized, more or less. However, your drinking is clearly beyond social and you are almost certainly alcoholic. You need help before you do permanent damage to body/mind.
