That's rather soon, the test is likely to be positive for about a week after use. The hydration does a little to speed elimination but it does a lot to lower the concentration of the drug in the urine. WHich is why they have cut offs for concentration of urine (if the urine is too dilute, they often say the specimen isn't valid for the testing). The urine of people I send for drug testing is on average HALF the concentration of the diabetics I send for urine testing of kidney function.
Good luck ! (and quit using drugs?)

Unlikley. On average we expect it to be positive for about 5 days. Hydrating helps slightly BUT it and other ways of duping the test are screened for and will be detectable.
