What do you drink before you start trading?

I'm interested to know what you drink when you wake up and also just before and while you're trading. Are you a coffee person or tea person? Do you find that one of these drinks is better for trading. I'm sure that a lot of traders take something with caffeine in it.

Personally, I start off with hot water with a bit of lemon in it when I wake up. Then at the market open and during the day I'll drink either water or fruit smoothies. Sometimes if I feel I need a kick of energy I'll have a caffeinated soda or coffee but that's rare.
