I have been given Morphine after surgeries and recently in ER for unspecified pain. I warned the ER Dr that it gives me hallucinations, but he went ahead anyway. I find the Morphine minimal in resolving the pain and have to decide to let go of all outcomes and accept that I will not be reliable or functional until the morphine wears off. Then I can just sit back and enjoy the hallucinations like a good movie. My hallucinations last long after the doses are given, up to 3 weeks. Since these were hospital IV administered, I have no idea of the dose. I just know that I do not want to take it long term.
