Depends on several factors but usually no longer than 24 hours, especially if you drink tons of water.
Depends on the amount you drank. It's a shot/drink and hour.
2, 3 days at most.... As long as you drink at least 3 glasses of water and piss a lot... Lol good luck
Wait like 5 days at the most way longer than 12 hours or even 24 yeah give it a few days or hey don't drink right before a drug test smart one
