I am confused on cumulative alcohol. I have been drinking daily for about a month anywhere from 6 to 12 beers. Yea I relapsed. Anyhow I drank 8 beers WednesdY July 9th and was done by 7:30 p.m. and bac should be at 0 by 7:30 Thursday a.m. I then had coffe with Baily's and done by 6:30 a.m. Thursday as well. You talk about alcohol not being cumulative yet the more you drink the longer ethanal to leave your body. Ok I broke down THursday night and had 3 beers from 7:30 p.m. to 9:30 p.m. again my bac should be at 0 by 2:00 a.m. Friday. I did EtG test Monday at 3:15 p.m. with an 85 hour window with 0 bac. I am a chronic drinker, female 45 years old 152 lbs and in fairly good shape for my age. Very demanding job walking about 7 miles on day on job. When do I start calculating time? When I drank the most at around 10:30 a.m. when the baily's wore off or the 3 beers in the evening on Thursday... friday morning? I had a true 85 hours no drinking. With this history can I
Pass the EtG?

You are taking an ETG for a reason and even if you do pass, please consider serious attention to your alcoholism.

You do what you are told,. stop altogether... You wouldn't be getting random tests if you were allowed to drink at all.

Sorry but if you are at all concerned about what will happen when, not if you fail a test, you will stop and make all efforts to stay dry. Your body will thank you for it.

At 85 hours, you will have no problems passing your test. The ETG will have passed out of your system by then.
