If you suffer from insomnia, you know how lousy it makes you feel.  But a new Harvard study shows just how much it can affect your productivity at work.

The statistics show that insomnia-related presenteeism causes the average U.S. employee to lose the equivalent of 11.3 days of work every year.  That adds up to an average annual loss of $2,280 per person - or about $63.2 BILLION - in lost productivity across the population.
