Coffee! Colombian - my friends used to bring me back the real thing when I lived in NYC. Black. No sugar.

I have 2 cups per day. I am allowed no more after recovering from a 40 - 50 cup per day addiction. It took six months to get rid of the dull caffeine headache. 24 hours a day even in my dreams, my head throbbed.

But when others order dessert I much prefer an expresso. My main vice, I think.
