Myth: Drinking coffee will help sober me up.
Truth: Only time will sober you up. Once alcohol is in your blood, there isn't anything you can do about it but wait. Coffee might wake you up, but it sure won't do anything about your blood alcohol levels.
Myth: Eating breath mints will fool a police 'breath test'.
Truth: The breath test is not fooled by breath mints. Blood alcohol measurement devices measure the alcohol content of the air in your lungs - breath mints will not change the alcohol content.
Myth: Eating certain foods before an evening of heavy drinking will help keep me sober.
Truth: Certain foods may slow down the rate of absorption of alcohol into your blood. However, the alcohol that goes into your body will come out in some form or another. If you're eating a meal to limit your drunkeness, think again - that's a bad idea.
Myth: Taking a cold shower or splashing water in my face sober me up?
Truth: No, it won't. While it might make you feel fresher or more awake, it has no effect on your blood alcohol content. Don't use this as a means to sober you up, because it doesn't work!
Myth: Physical activity will sober me up.
Truth: Exercise, because it speeds up your heart rate, may have a marginal affect to sober you up. However, this affect is so marginal that it's almost negligible in the grand scheme of things. If you had enough time to get drunk, wait longer and stay safe. It doesn't pay to drink and drive.
Myth: If you can't taste the alcohol in a drink, it's not there.
Truth: Some mixers, such as fruit juices, can mask the taste of alcohol. Also, certain types of alcohol (i.e. alcool) do not taste very strong, but the alcohol is still there. The best policy is - if you're drinking, don't drive!
