What exactly is Caffeine?

Caffeine is actually a psychoactive drug that works in the nervous system to block the signals of adenosine, which makes you feel tired. With the effects of adenosine being minimized, your brain is more alert, helping you to stay awake when tired, but also to help you feel more energized when you are not tired!
