An open bar at a wedding reception can be an open invitation to trouble for those who do not imbibe wisely. As tempting as it may be to take advantage of free alcohol, keep in mind that becoming overtly drunk isn't at all appropriate for a wedding.
There's a fine line between sipping in a controlled manner and drinking so much that you end up intoxicated and disruptive. Instead, save yourself from potential embarrassment by setting a limit on the amount of alcohol you consume. A cocktail or glass of wine may be fine, but one too many martinis could end up ruining the newlyweds’ big day.
