What do writer's drink?

I'm sitting at Panera waiting for Nora so we can critique our work and hopefully brainstorm me through the ending of my WIP. As I sit here drinking my Mountain Dew, I started to wonder what do other writers drink when they're in the creative spirit. For me, there are only two things that boost me along. Mountain Dew during the day or a lesser caffeine soda if MD is not available, and a Corona Light when I'm writing at night.

Occasionally I'll drink a Caramel Apple Spice from Starbucks when I can get it, but that's not as often.

What do the rest of you drink when you lock yourself away to write?
