How long does alcohal stay in or show up in urine
"Depending on how much you drank here's the facts: Expect each drink to take about 1 hour and 20 minutes to get through your system and into your urine. In addition to the 80 minutes per drink, the breakdown products of alcohol may be detectable for 24-48 hours after the last drink. And there nothing you can do to hasten the metabolism of alcohol in your body once you've had too many."
Depends on how much you drink, how often, etc but usually 1 hour to perhaps 10 or 12 hours
