Barack and Michelle, peanut butter and jelly, and now folks, Espresso and Emergen-C. I tried it as a joke moments ago, and found that as disgusting it sounds, it's actually not that bad. A quick jolt of caffeine added with some hot vitamin C action and I'm on cloud 9. I must say however, the last sip is a tough one with all the citrus. Strangely enough, I've already completed three days worth of work and jogged 2.5 miles, it works!
