The US economy lost about $249bn (£160bn) in 2010 due to the effects of excessive alcohol consumption, with binge drinking accounting for $191.1bn, or 76.7 per cent, of this. This was due to lost productivity, healthcare and other factors such as crime.
But the effect of a heavy hangover on a worker's productivity is the biggest contributor to this, costing $77bn.
