I'm going to a costume party tonight. It is byob (which is good) however I need suggestions on what would be good to drink. I don't do well with carbonation so beer is out :-(

Bottled water...

Not sure how far out you are, but if you want to indulge a little, get some vodka and mix with a light juice. I use Crangrape light, and I just found out about Minute Maid 15 calorie juices. Not that I'm condoning drinking in the early stages, but I know people are going to do what they want, and I drink occasionally.

Crystal Light has some new cocktail flavors such as Margarita and Mojito, maybe mix that with some bottled water and pour into a regular cocktail glass. That's what I'm going to do when I go to a party with drinking.
