Caffeinate

On the basis that no matter what anyone says about coffee, one is still likely to drink it - here are some figures on what's likely to fuel/fry your brain most. For me, more than one cup of filter coffee in any 2 hour period and I start to oscillate, bodily, and talk fasterandfastandfaster. So I'll stick with where I am. But notice the pointlessness of energy-boosting-fizzy drinks compared to an espresso!
