I love coffee! For me its not related to the caffeine because I will happily drink decaf (I know its never 100%) and can and have functioned without coffee. I love the taste, the smell, the culture, trying coffee from different countries.
I drink a coffee inthe morning and one in the early afternoon (small espresso sized cups). However I make italian coffee. I have read that it actually has less caffeine. Something to do with caffeine being water soluable and the coffee in the italian caffeteria (kettle-like coffee maker) doens't actually spend that much time in the water pushed through. Unlike American/German coffee machine where the coffee steeps in the water until the water drips through. I have not validated this though. =)
