If I had eight light beer bottles on Friday night over 2 hours, 12 ounces, what I be okay on Monday morning at 8? I stopped drinking at 7 pm. Please--any input would be helpful!!

The ETG test has a cutoff at 100. So worried!!

Need your gender and weight. That's four beers per hour, is that correct?

Yes sir. Female. 110 pounds. 5'2. I drank four beers per hour in two hours.

That could be a problem. Your BAC would have peaked near .30. The clearance time for the alcohol in your system would have been in the area of 17-18 hours. While there is alcohol in your system you are still creating EtG.

Nonetheless it's possible you could pass based on a couple of similar reports from people on this site:

55 hours from last drink, 15 drinks (3 bottles of wine), F-44-150 lbs >LINK
60 hours 8 beers, 35 year old female 5'4, 130 lbs. 500 cutoff >LINK

Based on the research to date you would need around 75-78 hours for EtG clearance. But that is an average and in such cases a number of people pass at far shorter periods.

I didn't think either of the above listed would pass, they are pretty close to or in excess of your consumption, but the test continues to surprise me for the number of false negatives returned.

So please keep me updated on the results

Does it matter Dr Bill that I consumed several (possibly 10) cups of coffee? The beers were Miller Light, and how did you calculate that I had a BAC of .3? I did not feel intoxicated the follwing morning, nor did I have a hangover. You see, I hate to be explicit, but I regurgitated a bit that evening. I apologize for that information. Please answer these questions, as I want to understand.

Back calculating BAC is always a pretty wide estimate. So if you didn't feel drunk next morning you probably have a very high EtOH elimination rate. Could be nearly twice what I figured. I calculated based on your gender and size based based on 5% abv beer and an elimnation rate of .017 ph being about average for female.

Miller light is 4.2% so that lowers the figure a little.

The liquid helped but is most helpful after the alcohol has already been eliminated.

As you can see others have passed at even shorter intervals. This test is very unreliable and unpredictable.
