Famed hangover cures are as old as drinking (give or take a few hours). What’s new is the aggressive marketing of them. And the authorities are not pleased by the development.

The Food and Drug Administration wants you to avoid heavy boozing altogether, but if you have a lapse in judgment (or plan to later tonight), don’t trust the folks promising you a miracle cure in the morning. The companies peddling Happy Hour Vitamins and Hangover Heaven’s Nightlife Prep Supplement (its IV hydration treatments, which are basically post-party outpatient procedures, have also been compromised) were threatened with FDA warning letters last week.
