How many cups of coffee do you have each day?

What sort of coffee do you have? How many cups a day? I used to drink instant coffee way too much, I was seriously addicted to caffeine. I broke the addiction by switching to decaff coffee and going through a week of mild headaches. Once I'd gotten over the headaches my addiction was broken. Now I have a proper espresso machine and drink the real stuff but I only have 3 or 4 cups a day, I don't have that physical yearning that the addiction gives you. I went from quantity to quality.
