How long does alcohol take to leave my body?

It takes ONE hour approximately for ONE unit of alcohol to be removed from your body.

 Just 4 drinks will stay in your system for longer than you think


  4 pints normal strength beer               8 hours

  4 pints premium strength beer            12 hours

  4 large measures (35ml) spirits            6 hours

  4 large glasses (250ml) wine              12 hours

Beware the morning after


It takes one hour for each unit of alcohol to leave your body - this means if you had eight pints of ordinary strength beer and stopped drinking at midnight, all of the alcohol would not be dispelled from you body (and you would not be safe to drive) until about 4 pm the following day.

 The only safe option is not to drink if you plan to drive.
