You’ve got to be careful in Las Vegas. The desert metropolis is the ultimate destination for reckless escapism and impossible dreams; wild promises in bold neon assault your eyeballs on every street corner. So I was pretty sceptical when I heard about a Sin City doctor who claimed to be able to cure any hangover in two hours flat.

Dr Jason Burke was working as an anaesthesiologist when he decided to pivot and become the world’s only doctor to formally dedicate his career to the study and treatment of hangovers. “Working in the recovery room, I saw various medications that we used to treat post-operative nausea, vomiting, pain, headaches and delirium,” he explains. “And I just thought these things could work really well for a hangover.”
