Over the counter crack

I'm not a big coffee drinker, but I felt the need for a jolt this morning so I stopped at Starbuck's and discovered the Cocoa Cappuccino. I ordered a tall and drank it at my desk - a bitter taste, but the energy boost was noticeable. Wow, and I really hate forking over four bucks for a small cup of coffee, but I'll have to give it another try soon. Of course, now the freaking thing has stayed with me all day and sleep is going to be a problem. Or, maybe it was just a coincidence and this is just a mood swing that had nothing to do with the coffee. Hm.
