Would you consider an IV drip to immediately cure your hangover?
basically, call the "hangover heaven" bus, AND A BOARD CERTIFIED M.D. (anesthesiologist) shows up, starts an IV with electrolytes, anti-nausea med, and anti-inflamatories, and the premium pack includes vitamins. Prices range from $90-$200.
I've heard stories from ambulance drivers and paramedics and medical students that a simple IV fluids dose cures a hangover in minutes... they would often take one right before their shift started.
I'm not that prone to hangovers, just some nausea for a few hours if I overdo it, so I don't see myself using it, but I know people who's hangovers can last 48 hours and they would probably get their money's worth.
