Consider taking L-theanine with your caffeine. When taken with caffeine, it smooths out the jitters and produces a subtle sense of clarity and focus; it will probably improve your ability to think on less caffeine. http://www.sciencedirect.com/science/article/pii/S0301051107001573 http://www.sciencedirect.com/science/article/pii/S0301051107... (Lots of other articles about the effect cited in https://en.wikipedia.org/wiki/Theanine https://en.wikipedia.org/wiki/Theanine too) If you are using caffeine for energy, you probably should improve your diet first, instead, and make sure you get enough sleep (which I know can be hard in crunch mode, but it makes your awake time much more productive). I love my coffee as much as the next person, but using caffeine to drive my ability to work has never produced good effects.
