Pain
"Twice within a calendar year I was admitted to the ER with gastric distress, accompanied with nausea.
Dilaudid was used the first time, the pain went quickly away and my nausea stopped.  The second time I was given morphine, but it did not work.  I asked for Dilaudid specifically.  It was given.  The pain and nausea went away.  I was able to rest/sleep, and after a couple of hours I felt fine, and played golf the next day.
For information, alcohol was involved with the first episode but not the last."
