Have you tried caffeine free Coke, Suzy? I drink caffeine free diet Coke when I have my insomnia spells (not nearly as scary as it sounds, hehe), but I'm sure they have caffeine free regular, and it doesn't taste too bad.
OH! Coke Zero, isn't that what it is?! It's caffeine free, right?
Definitely nothing fried, fried foods clog your arteries AND slow down your metabolism, as well as filling your system with nasty fats, carbs, and sodium. Drinking water is AWESOME, it's healthy, plus it flushes all the toxins from your systems AS WELL as calories, and as the icing on the cake, it makes your hair shiny and your skin clear. Can't go wrong!
