I find coffee products to be a frustrating product category. At least for me, I have adverse reactions to certain blends of coffees--particularly nausea, coldness, and headaches--while other ones don't cause trouble at all, so I have to try different coffee blends with a bit of caution. I notice that any amount of coffee past the second cup in the morning doesn't really add anything to my alertness, productivity, or ability to pretend to be a morning person--with the bulk of the benefit being from the first cup--but anything past the second cup makes it harder to fall asleep later at night. I can only imagine how one gets so far as to put down a pot of coffee a day (and then some!) for years on end.
