So Much Energy At Work!

I work the night shift at a warehouse, and let me tell you, it's pretty quiet. Most of the time I'm just stacking boxes and sorting stuff like an automaton. But tonight? Tonight is different. My hands are tapping away on my clipboard as if they have their own mind. I keep humming that stupid tune from last week’s meeting where we went over inventory counts. And to top it all off, there's this weird urge inside me to shout every time I stack a pallet of goods. It’s like a rush of adrenaline just for doing my job. Is anyone else out here with the same experience? Am I just going crazy with too much caffeine? What should I do to calm down?
