Caffeine is a methylxanthine present in tea and coffee, and therefore probably is the most common drug, regularly taken, in the world.
For all of its wild popularity, caffeine is one seriously misunderstood substance.
Caffeine is not a simple upper, and it works differently on different people with different tolerances. But you can make it work better for you.
