My doctor is currently weaning me off Fentanyl patches due to “fentanyl scare” as well. Been on 150mg for 12 years due to severe chronic nerve pain in my lower lumbar, facet joints, and legs/feet. I’m now on 125mg every 2 days and I am scared of what the withdraws are going to be like as well as what to use to replace fentanyl for my pain. I was at our Pain Clinic here in Nova Scotia, Canada, yesterday; and they suggested Cymbalta. Does anyone know the side effects of this, and is it an appropriate substitute for my chronic nerve pain.
