A warning to everybody recently prescribed with morphine. It will make you very constipated, however because morphine stops the muscles in the upper gut from working, this will not feel like constipation. Keep a diary of when you 'go'.
This make sound like a scare story, but I would not want anybody to go through what I did. I got really constipated, and the medicine I was given was better suited to preventing constipation, than relieving it. The medicine starts the muscles in the gut working again, and forces everything in the lower gut out. I would like to say that there was only one way for it to get out, but after one partiucularly painful night this was no longer the case. I was in severe pain, and thankful for the relief offered by the morphine.
