Parties are often a chance to relax, let loose and have a few drinks. Nothing wrong with that. But in some circumstances it's best to limit your intake for the sake of your personal and professional relationships — and that can be good news for your health.
According to etiquette experts, you should take your cues from the person drinking the least. That means if someone isn't imbibing, everyone else should limit themselves to three drinks so all guests are more or less equally coherent [source: Echlin]. Watching your consumption is particularly important at work parties, where excessive drinking can have professional consequences. A two-drink limit will keep you from saying or doing something you'll regret the next day in the office [source: Zimmerman].
What does drinking less have to do with your health? For one, alcohol's not the best use of calories. At 153 calories per 12-ounce (355-milliliter) beer, too much could begin impacting your weight [source: NIAAA]. There are also health risks associated with binge drinking, which the National Institute on Alcohol Abuse and Alcoholism defines as four or more drinks for a woman and five or more for a man in a two-hour period. Not to be a buzzkill, but this level of drinking is associated with high blood pressure, stroke, liver disease, neurological damage and other problems [source: CDC]. Moderate drinking, on the other hand — defined as two drinks for men and one for women per day — might actually be good for you [source: Harvard].
