Marty, can you update us when you experiment with hydromorphone?
Maybe this would be something to do with your 99-year-old grandmother, who you said was in pain. Have her see a pain specialist. If they prescribe her opiates to use, maybe do them with her as a bonding experience. I think this could be a good thing if she is in her last ten years, which I think is pretty likely, at age 99.
