Water, excellent teas (gotta keep my British side happy), and iced coffee for non-alcoholic drinks. As for booze, I go for dark beers, red wine, vodka with anything not too sweet, or basically whatever comes with the gig :p *classic musician/student perspective*

I drink, water and diet coke...dislike tea, hate coffee..

 

Vodka and lemonade or Peach Schapps and Lemonade, or all three

 

I also like cocktails
