How long is wine detectable in urine?

Alcohol is metabolized by what is called as 'zero' order kinetics. It means the rate of drug clearance is fixed without regards to the plasma concentration. Suppose a man drinks about 375 ml of whisky. (40 % alcohol.) He will have 150 ml of alcohol in his body. So every an hour he will have 10 ml alcohol metabolized from his body. So even after eight hours of sleep, he will have enough alcohol (70 ml.) in his body, to declare him intoxicated.
