I am just wondering about vodka. I love a vodka soda with a lime or lemon. Refreshing summer cocktail, right? So I am thinking there has to be a carb or 5 in a shot.... After looking up multiple nutrition facts, there are none. There are 80 or so cals, not from fat, or carbs? What? Where are the calories coming from then? No sugar? Isn't it a grain alcohol? Is the internet confused? Or is it jsut me?
