For the basic no frills test how much water to drink if taking shortly after ingesting alcohol

It doesn't matter. You will either fail for alcohol or fail for dilution. A fail is a fail.

Simple.. use ZERO alcohol or products with alcohol and you will pass the test. Otherwise... its your own fault when you fail. It was a choice and a risk you decided to take.

You cannot cleanse your system following alcohol use without risking dilution/masking. By trying to hide alcohol use you still fail.

Simple science.

Alcohol is Alcohol there is no way to stop it absorbing into your body after ingestion.

Drinking water may ever so slightly speed up the removal of the alcohol from your system , though like I said above will not stop the alcohol absorbing into breath and blood.

The only way to decrease amount of alcohol in blood is by a medical saline drip which is used in some cases to sober up a person who has had way too much Alcohol, though you would still fail any alcohol checking tests.

Hope this helps.

Does not work like that, water goes though system, the alcohol is absorbed into the blood system.

Drinking too much will also cause failures on the test for diluted sample.
