i had morphine drip, had to press the button to get a dose, nurse came in cause my BP was high, i was in pain, she said ive never known anyone not to keep taking doses, i told her the nausea was worse than cramping, some asshole orderly seemed put out to give me something to vomit in, he came back with this long plastic bag which i promptly filled, and handed it to him not the nurse with her hand out , guess i have an aversion to it, but i know its a vital drug, that twilight drug they gave me was great, my 45 min surgery that took 4 hrs, but i felt like it was an hour, but yeah i dont know why the morph was so horrid on my tummy, guess no tolerance, only time i ever was in the hospital, bet id press that button now!
