I'm a coffee drinker who manages to get away spending almost no money on it because coffee's free at work and I'm not picky about the taste (I don't mind instant). :) (it's coffee connoisseurs who spend a lot) I used to be a non-coffee drinker-- and I applaud coffee-teetotalers--but in my 2nd year of grad school I discovered that a small dose of coffee (1/2 cup) made so much more productive. Because I dosed it according to my body weight, I was able to get the benefits of coffee without its downsides. There were higher order benefits too. My moods improved because I felt productive, which helped me progress academically, and it all became a virtuous cycle. My rule today is: drink coffee, but not too much, free is better.
