The Pepsi Coke Paradigm

In the summer I become less an less a fan of morning coffee consumption. While some would take a leap towards Iced Coffee I find it rather gross as I hate milk in my coffee and black iced coffee is just effing rediculous. If I were wealthy it's possible I would purchase Venti Caramel Frappucinos from Starucks (I hate the bottled Fraps). But I'm not so I get my caffine fix in soda form. Here's the paradigm, I'm a Pepsi Drinker but in the morning I drink coke. I haven't a clue why. Pepsi in the morning just feels wrong. Try it you'll see what I mean.
