green tea for me
if not, try
water D:

I can't think of anything unless you grow your own tea herbs.
For myself, I like to use sassaphrass root with some honey.

Beer.. sorry for the cliche... Just don't drink too much you start to degrade after whatever your limit is. I usually find 4 or 5 beers is my sweet spot where I get into a groove. Combined with music is also super beneficial to me.

Thai iced tea, or an Irish coffee.

booze, it gets you all loose for the draw.

try tea or simple plain water.

and oh yeah i forgot, music helps things move along as long as its not distracting.

booze.
