There is a limit to how many receptors you can have, which limits how much "wakeup" coffee can produce. Once you hit the limit and fill them up, the only affect you get from more coffee are the negative problems. I vaguely remember it being like 400mg of caffeine or something like that.

400mg is about 3-5 cups of coffee a day depending on the roast.

  Except at Starbucks, where their coffees are large and strong! Tall 260mg Grande 330mg Venti 415mg

    Venti=20oz, a 'cup' of coffee is typically considered to be 5-6 oz, so the numbers still line up.

      It's also three shots (by default) making the lining up even clearer.
