There are receptors on your brain that gather a hormone that your body produces. Over the course of the day, your body produces this hormone a little at a time, and it attaches to the receptors. Caffeine replaces the hormone on the receptors and keeps you from feeling tired, so your body thinks something is wrong and makes more receptors. So after caffeine your brain has a higher capacity to feel tired. Sorry I don't know the names of the receptors or the hormone, I learned this so long ago that the names faded away.
