4: Stuff yourself before you goIf the dinner party invitation says cocktails start at 7 p.m., this probably means that dinner won't be served until Dave Letterman is delivering his monologue. As the evening wears on, even the wallpaper will start to look tasty. In this ravenous state you are likely to stuff yourself with too many hors d'oeuvres at dinner.
Tip: Nibble on something healthy before you leave the house - a large salad or a bowl of hearty vegetable soup. This tactic will curb the temptation to eat the mountain of cheese and crackers that are typically at holiday parties.
