What biological processes cause me to actually feel more tired if I drink too much caffeine instead of just more energetic?

Caffeine blocks adenosine receptors. Adenosine is a neurotransmitter that promotes sleepiness. When caffeine blocks the adenosine receptors, it prevents the neurotransmitter from binding and having its effect, leading to increased alertness.
