    Hi I was on 200mcg of fentanyl patch and 800mcg of the abstral (Fentayl oral) every 4 hours and also 100mcg nasal spray. I was total hooked on this drug I was a time bomb waiting too go off. I don’t have cancer but I have lots of other conditions which cause me horrible amounts of pain. Anyway I am under a palliative care for my pain management. We decided to start withdrawing the patch first and then the abstral and replaced it with liquid ketamine. Anyway I’m no longer on the abstral and staying at 75mcg of the fentanyl patch, the ketamine has now gone and I just have the patch and oxynorm for breakthrough pain it’s not been easy and I did it so there is hope to anyone reading this”
