Until they figure out your course of treatment ypu get Tylenol and advil. Once they decide an operation is not happening that day, you can get the good stuff.
When I broke my leg, I got tramadol and 1mg hydromorph. I can understand the appeal of hydromorph after taking them. Still have a handful in case they are needed.
On that note, almost everyone should have a lockbox for heavy drugs. Kids make mistakes and/or people have demons we do not know about. A lockbox with a hidden key limits access. It doesn't need to be amazingly secure but it must be obvious if it was accessed. Hopefully the person survives their first indiscretion. Loose bottles means you don't know what is going on for quite a while.
