I drank a pint of vodka (375 ml) this past Saturday evening at around 6/6:30pm. I have an appt with my doctor at 12noon on this coming Friday, and tests done at 1030am (also this coming Friday). I have NOT consumed any other alcohol since then. I am 6'5" and weigh around 280. Am I OK?

You should be. You have at least 100+hrs since your last drink so all the metabolites and the like should be out of your system.

Just in case, what do you stand to lose if you fail the test? Was the vodka worth it?

My doctor won't support me any more... I have cancer.

You should be clear by then.
