Getting back to 0.00%

There is nothing, aside from TIME, that will affect the rate at which alcohol is processed through your body. 

Alcohol leaves the body at a conservative rate of approximately 0.015L alcohol per hour or .015 percent of blood alcohol content (BAC) per hour. This is the average rate at which a healthy liver can metabolise alcohol. The result is that it can take many times longer to sober up than it took to become intoxicated. 

Hours to rid the body of alcohol = Peak BAC / .015

Someone with a BAC of 0.160, or twice the legal driving limit in Australia, will require over 10 hours to be completely sober and after 7 hours may still not be under the legal driving limit. 

Many late night revellers never think about the time it will take them to sober up completely. Driving or performing safety sensitive duties the morning after a big night out can put anyone at risk. If a persons BAC content is 0.200 after an evening of heavy drinking and stopping at 1:00AM, they may still not be under the legal driving limit of 0.050 BAC until approximately 11:00AM later that morning. A probationary licensed driver, learner driver, restricted driver or driver of public transport vehicle would not be OK to drive until after 2:00PM in the afternoon. 

There are a lot of variables to take into account when tracking your BAC so if you are planning to drive the next morning, plan not to drink that night but keeping a Calibrated Alcosense Breathalyser with you will give you options and the chance to make an informed decision the next morning.
