This is what I managed to find when I did a quick search.
As you have learned before Caffeine stimulates the central nervous system and can produce other effects through out the rest of the body. The symptoms of a caffeine overdose ("caffeinism") varies according to individual differences and the amount consumed. Doses ranging from 250 to 750 mg (2 to 7 cups of coffee) can produce restlessness, nausea, headache, tense muscles, sleep disturbances, and irregular heart beats it can also cause Anorexia. Doses of over 750 mg (7 cups of coffee) can produce a reaction similar to an anxiety attack, including delirium, ringing ears, and light flashes. These amounts of caffeine may come from a single dose or from many doses in a short period of time.
