I used to not drink coffee until a friend of mine introduced me to good coffee (i.e. not Maxwell House or Folgers). I normally only drink about 3 cups a week, usually in the afternoons, on busy days when I'm feeling sluggish. If I drink much more than that, I do notice that it loses its effect of waking me up, while simultaneously making it harder for me to sleep. It's kind of a shame, because I really enjoy the taste of good coffee now that I've found it. Making the perfect cup of coffee is a kind of art.
