Well, I'm a Coke man myself, but I'll drink just about anything, except Pepsi (too sweet and flat for my liking) and some other things...Slice and Squirt I can't stand, but I like Sprite. I always keep a supply of Sprites around for when I have a stomach upset, as Sprite tends to calm it down.
My wife, on the other hand, loves....Koolaid. Grape Koolaid, to be specific. She gets some every night before bed; she claims it helps her sleep better. Whatever works, I say.
Cheers,
