Dear 5 Hour Energy, how do I love thee let me count the ways. I love you because you instantly take me from feeling like I'm 68 to 19 all over again, I love you because you make me happy like a hippie in a daisy field, I love you because you make me feel rockin like Bon Jovi in 1986, I love you because you make me productive like Serpico even if the task at hand is rough. Love, Elisabeth Jane ♥
