I am a 165 lb female, I drank 8 beers in 7 hrs... I ate two big meals during... I took the ETG 39 hrs from the time I stopped drinking... During the 39 hrs I drank lots of water... My urine sample had just a hint of yellow... It was a random alcohol test I wasn't prepared for... If I fail they will take my driving privileges away :( is there anyway I can claim a false positive?

You are going to find out when the results come back. You are aware dilution is an automatic fail?

We however won't help you decide how much you can drink so you can continue. As per the site rules this site is for helping people overcome their addictions... not to help them pass tests so they can continue abusing their substance of choice.
