pain
"I have had this twice, both times it made me mildly nauseous and did nothing for the pain.  The first time was when I made a trip to the emergency room for a migraine. It was a terrible migraine.

 After about 15 minutes of me screaming and wailing in the emergency room it started to wane. It was very mild by the time the doctor came in to talk to me.  But he still gave me an injection of dilaudid.  And even for the mild headache it didn't help at all. 

 Second time was after hysterectomy. I had excruciating pain from trapped gas under my ribs near my liver.  Nurses kept telling me to press my pain med dispensing button,  and I was already. But it wasn't even taking the edge off."
