I have only once chosen to drink coffee of my own free will. I was visiting my parents house for a wedding. The day after the wedding I had the second worst hangover I have had in my entire life (the first worst is a story for another time), and the first thing I did when getting out of bed was go straight to the kitchen, take the coffee pot right out of the brewer and lift it directly to my lips, and I drank the whole thing down in one lift (there was probably about 4 cups left in it). It was black, it was cold, and it saved my life.
