Quite a bit but . . : While it could make you pretty nervous and sweaty it would take the caffeine found in 70 to 100 cups of coffee to kill the average adult. The big problem with caffeine is that it is addictive with a well-defined withdrawal syndrome (headaches, irritability, constipation) which many over the counter medications like Excedrin take advantage of. Cures the headache 4 hours after last dose or coffee.
