The morphine will help for sure, it will give the synthetic fentanyl
to leave your body. Definitely ask your doctor about a taper on morphine
. Google opiate equivalency and find how much morphine to start at, talk to your doctor about a realistic schedule. Fentanyl is stronger than morphine, so don't keep taking it until you feel good. That would be a lot. Stay at a tolerable dose until you talk to your doctor again. Did he give you any idea of how much to take?
