10 years ago i was in the hospital for appendix surgery was given morphine it knocked me out and when i was awake i was paranoid, crying, and felt like something was wrong with my head but could not explain it it was like nothing i ever felt before. i argued with all the staff at the hospital i refused to take my medicine and wanted to go home . i was on IV antibiotics with a ruptured appendix the hospital would not let me go home. i thought i was going crazy i started to cry uncontrollably. if i didnt come across this site i would of never thought the morphine caused this to this day i didnt know why i acted like that it makes sense now. next time i'll be sure to let the hosp. know of my side effect.
