Remember it takes at least 1 hour for EACH unit of alcohol to leave your body. Count your units when you have STOPPED drinking.
Add an additional hour for the first unit to allow for the alcohol to enter the bloodstream.
1 unit = 1 + 1 = 2 hours to wait
2 units = 2 + 1 = 3 hours to wait
This varies a lot depending on many factors e.g. gender, height and weight, age, your liver and how much food you have eaten. See chart opposite for more information.
There is nothing you can do to speed up the rate of alcohol leaves your body.
