I've been on Fentanyl patches and using Abstral for breakthrough pain from April. I'm about to have my last week of chemo before they decide if I'm on an end of treatment plan or more chemo. I'm keen to get off all pain meds so that I can know what "normal" feels like and learn to read the signs that something isn't right with my body. Really scary !! Dr had told me it will feel like going cold turkey but it's really tough ! My whole body is aching and I've a splitting headache. Has anyone else experienced this and if so can you offer any suggestions that would help ?
