Can you die from taking too much caffeine? The answer is yes - all it takes to kill you is the equivalent of 70 cans of energy drinks:
Previously on Neatorama: 30 Strangest Deaths in HistoryApparently, the pack of [powder] caffeine suggested taking no more than 1/16 of a teaspoon, but Bedford reportedly took spoonfuls of the stuff, so I wouldn’t start worrying that your morning coffee addiction might help you end up on the wrong side of living. Bedford reportedly took the dosage of caffeine at a party, and one friend recounts seeing him profusely sweating and throwing up blood only about 15 minutes after the dosage was taken. Pretty horrifying.
Anyway I've gotten to the point of serious heart palpitations and visual problems many times during college, so I have no doubt that it's not too difficult to OD on it.
I hope she waited for it to cool down!
