Between drinking too much water are there certain vitamins/supplements that should be avoided to not have a false-positive ETG test. I drink at least 4 gallons of water a day (sweat tons) and was about to start a new workout with supplements and vitamins now I have to get tested... uggghhh

Not to my knowledge. However, there have been no tests to make that determination.

Also, water consumption does not create false positives on this test. In fact it is very beneficial especially since you work out and take supplements, both of which can lead to creatinine in urine.
