This Entrepreneur Created a Hangover Cure on WheelsHangover Heaven s a 45-foot bus staffed with nurses and assistants to deliver patients a mix of medications, electrolytes and vitamins via IV.

Entrepreneur:Jason Burke worked as an anesthesiologist in Las Vegas for seven years before he decided to launch a company that would help people with hangovers get back on their feet.

"Aha" moment:While on duty in the recovery room, Burke—who still practices medicine a couple of days per week—realized that the same meds used to help post-op patients suffering from nausea, headache or dizziness could be a boon to the city's party people.

Tying one on:In 2011 Burke attempted to launch a business administering IV meds for hangovers from a location across from the Hard Rock Hotel & Casino. The financial realities of real estate on the Strip put an end to that. However, while driving around the city, he hit upon the idea of offering his services on the go, via bus. Hangover sufferers would get a remedy faster, he theorized, and he'd minimize his overhead. Nevada officials saw no problem with the plan, and in 2012 Burke launched Hangover Heaven in a 45-foot bus.
