I had the same exact same experience as Russ. Got morphine injection after an operation and all my physical and mental pain was gone. I felt totally at peace with the whole world and myself. I also asked to have another one the next day, but they would only give me tablets which I declined. I cannot believe it either, asking for more as I am totally against any form of drugs and medicine, even alcohol. I got the morphine injection about 7 years ago, but I have never forgotten how peaceful I felt.
