I will never understand why people want to mix a lot of stuff together just to get a drink... my favorite is easy, warm and u go off with a bang:
First one vodka shot (no mix match...just pure vodka - 4-6 cl)
Then you have some Perrier (its in a glass all of its own)
Second vodka shot
Then some more Perrier
Third and fourth vodka shot (u have warmed up by now so two in a row is a piece of cake)
and so on... till u get happy enogh
Then u can just go with the Perrier for awhile
