Im 16, weigh 200 lbs and am 5'11. Itd be greatly appreciated because I'm kind of freaking out now. I plan on drinking a lot of water tomorrow

Why the test tomorrow?

Drinking lots of water is not a good idea.

Drinking water will not alter your EtG on Monday. You should have read up on this topic before Saturday Alcohol ETG Urine Testing Resources If you were having a ETS you might pass but ETG can detect for 3-5 days.

Whys drinking water not a good thing? And what's the difference between an ets and EtG test? I'm about to read up on that link you gave me. Thanks

Wallace, you need to start researching these topics, just Google them. ETS and ETG are two different test which produce different results, water does not alter the presence of alcohol, you can't flush your system.
