3-4 cups green tea a day (good to mix creatine with). You're drinking water and sometimes good anti-oxidants (great for cleansing your body after exercising, or during hangovers).

I try to stay away from coffee; it doesn't take me long to acquire a tolerance for caffeine. I just don't see the benefits of coffee.

I'm a huge fan of grapefruit juice and V8 too.

I usually had success with an "addiction reset" by going cold turkey after every semester as an undergrad. As a grad student, I've found that even though I drink 3 cups of green or white tea per day, which is supposed to have relatively minimal caffeine, I get headaches on the weekends when I don't have tea. Do you notice withdrawal headaches with that level of consumption?
