"i just had emergency gallbladder removal surgery. when i woke up from general anesthesia i was given a dilaudid i.v. the pain was still there. i begged and begged for a higher dose but was not given one. throughout the night and next day the moment the dilaudid was injected in the i.v i would vomit. i had to keep my eyes closed for most of the morning. even with anti-nausea injections the dilaudid had me vomiting. in regards to the pain it lasted only about 2 hours and then the pain was back. i had them stop administering it to me."
