Bests & Worsts Reviews from Amazon

I am an avid coffee drinker, but there are times when it's inconvenient to go get it and/or expensive (Starbucks especially). This is great for both morning upon first waking up, as well as that afternoon pick me up. I have taken it as late as 5pm and have had no issues falling asleep. The first day I tried it, I took it after a big meal and didn't feel very energized after, but the next day I discovered that it's best on an empty stomach. I have noticed that I feel the most effects first thing in the morning on an empty stomach, or at least 2 hours after eating. I am a student and it has helped me focus better, it's also improved my workout focus and energy! I have experienced no jitters, no headaches, no digestive issues. I'm happy with this product!
