Okay, the seven hour stuff has enough caffeine that you would find in one cup of coffee. This stuff didn't make me a complete nervous fup. No more of the six hour, two cups of coffee crap. I'm going to give away the second one that I have, or have it in place of coffee in the morning. But 5-Hour Energy is still the best.
Other running notes, I am going to sign up for a half marathon tonight. Wish me luck, as of right now I have never run more than 10-11 miles in one day in my life.
