As many of us know in hospital when we are administered Morphine intervenously we are also given cyclizine to prevent sickness. I am used to the huge pleasent cold sensation through his body followed by the fuzzy warmness that he gets when he goes into hospital and is given IV morphine for his pain. What I didnt realise is that the very pleasent cold sensation up his spine is infact not created by morphine but by cyclizine. When I was administered cyclizine alone he still got the pleasent rush up his spine from it without the fuzziness after. Is cyclizine suppose to create this reaction? I found this very pleasent but very phychologically addicted especially since it only lasted 10 - 15 seconds. People talk of the morphine or heroin rush, im not sure that this exists as once I was given the morphine without the cyclizine he experience no rushing sensation.
