Cold water
Kind of Drinks!

Coconut Water and Chilled butter milk .. a lot of it 
Mineral water or chilled green tea, the latter is conveniently available in a can from all soft drink vending machines and there is certainly no shortage of those where I come from 
Cold water with freshly squeezed lemon juice. Even iced tea usually does the trick
Plain water, I'm sensitive to cold things.
