"I thought that received wisdom had it that Tea quenches thirst, Coffee aggrovates it? Bit of a problem for a coffee addict like yours truely, what?"

I've heard that coffee is a diuretic, meaning that it causes you to pee more than you would otherwise. That means you lose fluids by drinking it. I'm not sure tea is any better since I'm thinking it is the caffeine that causes the problem. Tea does have less caffeine than coffee however. But the Decaf coffee bags I use have less caffeine than tea does.

At this point a doctor needs to chime in. <img src="/images/graemlins/shocked.gif" alt="" />
