I had open heart surgery in the US and the doctors refused to give me opiates to take home in the few days after. They gave me opiates while I was in the hospital, quite generously, which was for four or five days, but they would not let me take any home. I even asked for just five pills in case the pain was unbearable (they literally had just broke my ribs and sternum and sawed my chest open). I don’t respond much to opiates anyways, but I still find it completely ridiculous.
