Introduction ~ Question on when to try weaning off meds

Hello~ I am a chronic pain sufferer for 7 years. Started after stem cell transplant for an aggressive lymphoma and got much worse after a second one. I am 54 and still grieve what was an am trying to adjust/accept the "new normal." I am in remission, but the alphabet soup of chemo, radiation and two stem cell transplants have left me a shadow of what I once was. My pain is bone and sometimes joint and sometimes all over myalgia. I am on oxycontin 20 3x day and norco 10/325 for break-through pain of which I take 4/day some days six, some days 2 or none, but average 4. I also use medical Marijuana for sleep and really bad days. I started Cymbalta to help with neuropathy in my hands and feet and that helped my overall myalgia pain as well. Here is my question, my palliative care/pain management team is talking about trying to cut back. My thinking is that if I have to take Norco the vast majority of days, cutting back will only increase break through pain. Thoughts, experiences? I live in fear of losing my meds as I was suicidal before I was finally appropriately treated. Help! and Thank you!
