This would be basically why after breaking my hip and having it reassembled around a Dynamic Hip Screw, every week I dropped my dose of codeine so that the pain was back to being as bad as I'd been dealing with a week ago. I do wish people being prescribed opiates for situations where that's possible (i.e. the pain will lessen over time anyway) basically got a guide on doing that, not everybody's an ornery bastard like I am.
The only time opiates for control of pain that wasn't going to lessen over time seems like a good idea is in the case of palliative care for the dying; my father got several months of mostly-pain-free end of life out of it, and whether it was increased pain from the cancer or decreased effectiveness due to addiction that eventually meant the maximum dose allowable didn't help, he was dead within a week after that so even given all the obvious caveats I think he picked the right set of trade-offs.
