In short, if you want to feel not only alert but also ready for action, merely ingesting caffeine won’t cut it. You will need that full coffee experience.

Factors like coffee’s distinctive aroma and taste possibly drive this finding. Or the psychological expectations tied to the drink could play a role.

I drink a monster every morning and it barely does anything. Then again, I’m on drugs that make me sleepy.
