Iced coffee! Err.. your beverage of choice is..?

Yes, I am starting a thread about what your preferred all-day drink is. For those of you that like to walk around half-tanked all day, brand names and proof amount would be nice. For the rest of you.. what do you prefer to drink? I'm a fan of "home made" iced coffee in a 7-11 Double Gulp cup. Which is simply coffee (very strong), ice, and very sugary creamer. Barring that, black coffee.

And why would I start this thread? Simple curiosity of what keeps other firearms aficionados from being thirsty all day.
