You caught me at a good time. I just read the poisoning appendix in a medical
dictionary where it stated that caffine poisoning occurs at 5-50 mg caffine/kg
body weight. If you are 70 kg, and the average cup of coffee has 50 mg, you
could begin poisoning yourself with a minimum of 70 x 5 / 50 = 7 cups of coffee. 
Of course it will vary depending on your tolerance.
