12-ounce beer=1 drink

 How Much Is One Drink?
How many times have you heard someone say, "I can drive, I've only had a couple drinks"? Depending on what you're drinking, and the size of your glass, a drink may contain more alcohol than you think.

Keep this in mind the next time you're having a drink, whether it's out with your friends or at dinner in a restaurant: One drink equals a 12-ounce bottle of beer...
1 glass of wine=1drink

One Drink Equals
...a 5-ounce glass of wine, or...
1 shot=1 drink

One Drink Equals
...one shot of liquor.
1 Cosmo=2 drinks

A Cosmo
A typical Cosmopolitan or martini has at least two shots of liquor. So after one Cosmo, you've really had two drinks.

1 margarita=2 drink

A Margarita
The same thing is true for a typical margarita. One margarita has at least two shots in it. So when you drink two margaritas, you've really had four servings of alcohol.
Phase One: 1 to 2 drinks

Phase One
Now you know how much alcohol is in a common drink, but do you know how those drinks will affect your judgment? Or how many drinks make it illegal for you to drive a car?

Here are the four phases an average 130-pound woman can expect to go through over a two-hour period of drinking.

Phase One: Feeling Good. After one or two drinks, your blood-alcohol concentration is probably around .04. You feel more social. You have a warm physical glow.
Phase 2: 3 to 4 days

Phase Two
Phase Two: Buzzed. You have had three to four drinks. You can become socially uninhibited. You have impaired judgment and slower reflexes. At this phase, your blood alcohol concentration (BAC) is most likely above .08, the legal limit. You should not drive.
Phase Three: 5 to 6 drinks

Phase Three
Phase Three: Drunk. You've had five to six drinks. Now your BAC level is around .14. The average 130-pound woman is likely to have lack of concentration, poor coordination, unstable emotions and slurred speech.
Common misconceptions about sobering up

Phase Four
Phase Four: Wasted. If you've had seven or more drinks, now you're BAC is more than twice the legal limit. Women will be groggy and only semi alert in this stage and may even fall asleep or pass out.

The average woman metabolizes alcohol at the rate of about one drink per hour. Drinking coffee, exercising or taking a cold shower will not help a person sober up, only time will!
