I knew it blocked the adenosine receptors, but I didn't realize it actually triggered adrenaline and dopamine release. I guess that explains one of the reasons I get cravings even when I'm not tired. Makes me realize it is perhaps more of a drug than just a trick for staying awake and something with a good taste. Maybe it's time to re-evaluate my intake.
