I found this tip as I thought I would share:

Lose While You Booze

Eight hundred calories—that’s what you’ll be sucking down with your favorite restaurant’s frozen margarita. Booze can be a real diet killer, but that doesn’t mean you have to skip happy hour to stick to your calorie-counting guns. Being a little more selective when choosing your poison will help you to “Lose While You Booze.” Skip anything fruity and ask for diet sodas as mixers in your cocktail. Or for all the sippin’ (and only half the calories), why not try a white wine spritzer?
