After a big night out you may still be over your legal alcohol limit for much of the next day. After a heavy night of drinking, it can take more than 18 hours for your blood alcohol concentration to get back to zero.
Blood: Alcohol is eliminated from the bloodstream at about 0.015 per hour. Alcohol can show up in a blood test for up to 12 hours. Urine: Alcohol can be detected in urine for up 3 to 5 days via the ethyl glucuronide (EtG) test or 10 to 12 hours via the traditional method.
Generally, a breathalyzer test can test positive for alcohol for up to 12 hours after consuming one alcoholic drink. The average urine test can also detect alcohol 12-48 hours later. If your BAC is 0.08, it will take approximately 5 hours to metabolize the alcohol completely before you can become “sober” again.
In some cases, the breathalyzer may detect alcohol for up to 12 hours. In other individuals, the breathalyzer test may work for twice that long. Although the average person metabolizes about 1 alcoholic drink per hour, this rate varies.
For the average person, it only takes about three or four drinks in one hour to reach a BAC of 0.08. Given the general rule, if your blood alcohol content is at the limit of 0.08, it would go down to 0.065 after one hour.
After a heavy night of drinking, it can take more than 18 hours for your blood alcohol concentration to get back to zero. Many people are booked for drink driving the next day.
There is nothing a person can do to quickly reduce the blood alcohol concentration (BAC) level in their body. The liver needs time to filter blood and remove the alcohol from the system.
In general, a blood test can measure alcohol in your body for up to 6 hours after your last drink, while breathalyser tests work for between 12 and 24 hours. Urine tests, such as the ethyl glucuronide (EtG) test, are also effective for around 12-24 hours after use.
The General Rule of Thumb: One Hour Per Drink
According to the National Institute on Alcohol, you should wait at least one hour for each standard drink.
Wine: The average glass of wine can take 3 hours to leave your system, half of your favourite bottle can stay in your system for 4.5 hours, and the average bottle can take 9 whole hours to leave your body.
Contrary to popular belief, nothing can lower BAC except time; coffee, cold showers, and chugging glasses of water will not help you sober up any faster. Curious what your BAC might be?
Your blood alcohol level can still rise whilst you're asleep and lead to alcohol poisoning. That's the big deal… putting a drunk person to sleep doesn't automatically remove the undigested alcohol from their system. They're body still needs to process it and break it down.
It is important to note that common strategies used to “sober up,” such as taking a cold shower, sleeping, drinking water and consuming caffeine, do not work to lower BAC. The only thing that can help alcohol leave your bloodstream is time.
If you're going to work at 8am the day after a night out, and you consume 6 standard drinks between 8pm and midnight, you should be OK to drive and work the next day. If you drink one standard drink per hour, you should be under the . 05 blood alcohol limit.
A general rule of thumb is not to drive if you feel even the slightest effects of drinking. If you must take a drink or two, remember that our bodies metabolize one drink per hour. You might feel like you're good to go if you wait a few hours after drinking, especially if you dilute the alcohol by drinking water.
In a pint of 0.5% beer or cider, that works out as 0.28 units, meaning your body will be able to process this alcohol every 17 minutes. In other words, you need to be drinking four pints or more of 0.5% beer or cider per hour to go beyond your body's ability to process the alcohol.
Even though the person is sleeping, alcohol levels may continue to rise, causing the person to become unconscious, rather than asleep. If at any time you can not wake the person up, CALL 9-1-1.
Any food will help, but carbohydrates — like bread, pasta or potatoes — slow down how quickly your body absorbs the alcohol. Eating during or after drinking alcohol may make you feel less intoxicated, but it doesn't mean you've sobered up and are no longer impaired.
Alcohol dehydrates you, it's a diuretic, which means it makes you go to the loo more often. So, if you want to avoid that dreaded hangover, water is giving you a helping hand and keeping you hydrated.”
Whilst coffee can certainly make you more alert, it cannot 'sober you up'. Thinking so would be a dangerous mistake. It does not displace or get rid of the alcohol present in your system.
Drinking a bottle of wine a day may rapidly increase the likelihood of physical and chemical alcohol addiction developing. Drinking a bottle per day equates to approximately 9 units per day or 63 units per week, far in excess of UK NHS recommended guidelines (14 units per week)[1].
Health experts suggest considering a glass or two at a sitting and leaving two or three days between drinking. They advise against binge drinking and heavy consumption. The consensus is to make that bottle of wine last a week.
