What city are you in? Go get some Yerba Matte, the loose kind.
But about 1cm of it in the bottom of a french press, and about 2cm of milk in the bottom of a 20oz glass. Mix.
Then add a few squirts of peppermint. (like 4 squirts).
I'm serious, this concoction has gotten me through more all-nighter-afters than anything else ever.
