I can't drink straight coffe (only a tiny little bit with milk or in the quantities in a coke), I become "alergic" to it for no reason (i get sick when I drink an expresso, for example).
I don't like tea... It's like hot water. I guess it could be a matter of habbit.
What I find out a like to do while reading in my Cybook, is to be nibbling a piece of fruit. That one advantage of having an ebook: it frees one hand.
