Morphine is also less damaging to your organs than NSAIDs.
You may feel some strong side effects (dopiness, slight nausea) at first, but that usually resolves within a week or so.
If your concern is becoming addicted, there's a very low chance (less than 3% if you have no previous history of substance abuse or psychological issues). I'm actually more concerned (and curious) that they've got you on
TWO benzodiazepines. Please be careful when using with morphine! In fact, my hope would be that you remind your doctor of this, and ask if you should decrease/stop one or both of the benzos—at least until you're acclimated to the morphine.
