You may begin to feel the effects within 10 minutes of drinking, and they'll peak around 40 to 60 minutes after drinking. Factors — like how much you weigh and whether you've eaten recently — can influence how quickly your body absorbs alcohol. After alcohol enters the bloodstream it's broken down by the liver.

How long does it take to sober up?

It takes about an hour for your liver to break down the amount of alcohol in a standard alcoholic drink (one beer, one glass of wine, or one shot). If you drink alcohol faster than your liver can break it down, your blood alcohol level rises and you start feeling drunk.

Can you still be drunk after 12 hours?

Yes. Whether your blood alcohol is still above the limit depends on a number of factors. The main ones are how much alcohol you consumed last night and at what time.
