While working in the ER I've seen some impressive ingestions, both intentional and unintentional. I can guarantee that if he survives, it ain't gonna be a fun time. Off the top of my head, I think he'd be getting Narcan, Amiodarone, Flumazenil, cardiovascular and respiratory support, and probably hemodialysis. If he doesn't die from the cocktail, the hospital bill might get him.
