Also with regards to general, I too got very ill from it and it does take a while for recovery. It hasn't been as bad the last few times as they have given me less and I have now realised what drugs I can and cannot tolerate. Morphine although good for pain relief is awful for me. I ask every time not to have this and am prescribed something else. Whilst the relief isn't as great I don't feel so ill. I now recover much quicker - last time within a few hours. If Morphine isn't good for you also I would just tell the docs/nurse when having you pre-assesment. There are other drugs they can prescribe with less bad effects.
