I was reading this article on io9 the other day about coffee consumption among business professionals. In it they listed the 15 heaviest coffee drinkers by profession (in the United States). I was unsurprised to see “writers” near the top of the list, but I was completely surprised to see that web designers didn't even make the top 15. How much coffee do you drink per day? And if you don't drink coffee, but do drink caffeinated tea, please answer how much you drink of that instead. I can tell you that I drink at least two cups of coffee a day, sometimes more. I also drink green (caffeinated) tea and diet coke. It helps me type fast!
