Hi Diana,

I don't have any personal experiences with morphine, but I can relate a story about my wife's grandmother whom was admitted into the hospital for a relatively minor thing. She was the most polite and soft spoken little lady you could ever imagine all her life. Then they gave her some pain medications over night. She turned into something from a Hitchcock movie. Demons were seen, people out to kill her, relatives weren't to be trusted, and she got physical with the nurses. The nightime medical staff didn't know that this wasn't normal for her and continued to give her that same pain medication until family came in and said to stop! She returned to normal within a day or so and didn't remember anything about it.

The moral is some meds are bad for some people. I believe your dad will come out just fine. There are lots of other pain meds they can try.
