I've had a fair bit of morphine, most of it due to a climbing accident. MR gave me it straight off ("Hi, I'm John, I weigh 100 kilos, my GCS is 13 and can I have 10 mgs please?" "No, cheeky boy, we'll start you with 5") Post-op, after plastic surgery, I had 30 mgs in total, 2mgs every 3 minutes. "Can you speed it up at all? England - Argentina are kicking off!" Never mind, I was in time to see the Beckham penalty. Oddly, I'd seen the Maradona foul through post-op morphine in '86, after breaking my left leg. I don't like it much, it makes everything dull and soupy, and at high doses you become aware that the breathing reflex is depressed.
