The percent of alcohol in a person's blood. What you drink doesn't really matter. There is just as much alcohol in the average drink of beer as there is in the average drink of whiskey or wine. In fact, studies show the greatest number of people arrested for drunken driving had been drinking beer. Mixing drinks doesn't make you drunk.
Food does slow the absorption of alcohol.
This delaying action prevents large amounts of alcohol from affecting your brain immediately. And if alcohol is already in your bloodstream, eating won't sober you up. Neither will aspirin, black coffee, deep breathing, cold showers, a slap in the face or exercise. If you are not feeling well or are tired or upset, even small or moderate amounts of alcohol may affect you more. The best advice is if you drink alcohol, do not drive.
