As a traditional die-hard espresso drinker, I didn't think I could be swayed by the energy drink side. But since coffee tends to give a peak-and-crash type experience, I was open to trying Pocket Rocket based on a friend's recommendation. What I found is that it provides a much smoother and longer-lasting energy profile and it's my new go-to before a long work day or before a day in the mountain bike saddle or on the ski slopes. I also love the portability of it and the fact you can drink it by itself or mix it with something else. Give it a try - you won't be disappointed.
