I have been on Morphine for four years along with Oxycodone for five years and Flexeril for five years and Cymbalta for a year. My memory is getting really bad. My short term memory is what bothers me the very most. I can't remember things from one moment to the next. I have to set alarms to remind me to even take my meds. I always joke and say I suffer from morphine dimentia but recently someone told me that morphine does add to memory loss. Does anyone else have this problem or know anything about this? I would love any and all advice. Thank you in advance.
