Morphine Sulfate SR and shakes

Following an op on 12th Sept I was given a self administered morphine pump, (Safe measured doses??). Within 6 hours I was experiencing extremly dry mouth, and De-jevous (I knew what was going to be said or done before it happened.)Then the most terrifying hallucinations. My senses were wide open. I could hear every conversation in the ward and outside all at once and it was all going on in MY head. The smell of flowers at the other end of the ward was overpowing.
Along with this came hot and cold sweats even though my temp and pulse were normal. I had the shakes and was VERY confused and frightened and became paranoid. I ripped out all my tubes and phoned the police to say they were trying to kill me. The hallucinations lasted about 4/5 days and the rest about 3 weeks. All this was made worse by the fact that neither Docs or nurses accepted all I was going through. I had no sympathy understanding, counselling and was expected for the most part to look after myself.
I now have post traumatic stress due to how I was treated in hospital during this personal crisis.
