“A hangover comes in different forms. Everyone is different,” Dr. Adam Nadelson, CEO of the I.V. Doc, the leading provider of private on-demand IV fluid treatments and vitamin infusions, said. “Where we come in is when somebody is feeling really bad.”

The party-afflicted can choose from five hangover cures: the Cleanse, the Detox, the Refresh, the Revive or a Super Vitamin B injection. After booking online, a registered nurse arrives at your room at the scheduled time, fluid bag in hand. “We can help you feel better quicker,” Nadelson said. “It’s practically instantaneous.”
