How much caffeine should you drink? The amount that doesn't make you feel like shit.


"Hey honey, aren't you happy that we evolved to have the mental faculties to tell when we've had too much coffee?" (via Thinkstock)

Hey guys, look! There's a scientific report about how much caffeine you should drink! The European Food Safety Authority (EFSA) puts safe caffeine usage at 400 mg per day, which is about four 8 oz. cups or five espresso shots. Thank goodness you finally know how much caffeine you should drink (or eat on popcorn), because it's 100% impossible to tell how much caffeine is too much or too little just by consuming it!

Oh, wait. What I meant to say is that we human beings can totally tell when we've had too much or too little caffeine.
