　　How much is too much? It depends on how fast your body metabolises caffeine, but as a general rule: "A high dose of caffeine is 500mg per day, based on a 70kg adult, which works out at six to eight cups of instant coffee," says Karen Dickinson, of Body Acoustics Health and Sports Nutrition. "A moderate dose is 300 to 400mg per day; four to six cups."
