Question

I drank heavily  form saturday till Monday 4 Liters of beer each day.  I am being called to do a Urine test for etg on Thurday morning. What can I do to pass the test. Please help me. I have been drinking a lot of water since this morning and was also told to add cretine , vit B complex and Vitamin C. Are these going to help me? Before this weekend I havent taken alcohol for a very long time.
