drinking hangover

A company called ZBiotic wants you to believe that its product – a microorganism that makes the enzyme that metabolizes acetaldehyde – will help prevent a hangover. Should we believe this?
This holiday season, it s OK to be merry and bright, but remember that a night of drunken reveling can most certainly result in a holiday hangover the next day. And those bells you hear jingeling will only be in your head and they ll be loud.
