Hi Juju,
Thanks for being our guinea pig in the name of science!
I wonder if beer should be a separate experiment, though. I'm with you on the Vodka/Cranberries... I've heard that vodka is one of the 'cleanest' alcohol choices in terms of carbs and sugars.
Beer on the other hand, has tons of carbs/sugars, plus the carbonation factor. Puts more variables that can cause a reaction into the experiment. Back to to the lab!
