I drank one cup of vodka and cranberry juice on 09/17/10 around 7pm and I want to knoiw if it will be out of my system by Monday morning?

Most likely not, but what is the problem, it is not like you are not suppose to be drinking and will have to do a test is it ?

It takes approx 1 hour for your body to break down 1oz of Vodka.
