Your liver can process 1 unit an hour, so you'll be fine (or you should be). Also, your job doesn't allow you to drink?

It should work through your system at about a unit an hour, but thats a generalisation, it depends on your body. What level of alcohol is the maximum you're allowed in the test? It might not disappear completely, but it should go below the drink drive limit.
