Over time, your brain will start spouting more adenosine receptors in an effort to make up for what it’s missing — meaning that you’ll need to consume more caffeine to keep the sleepiness at bay, and you’ll feel increasingly worse when you don’t get it.

Proc Natl Acad Sci USA 98:9407–9412, Kaelin-Lang A, Lauterburg T, Burgunder JM (1998) Expression of adenosine A2A receptor gene in rat dorsal root and autonomic ganglia. Adenosine is able to decrease the release of most neurotransmitters. Thus, adenosine receptor stimulation provides a “brake” on excessive dopamine receptor activity that ultimately influences drug-induced changes in neuronal function and behavior.
