I am currently on 40mg OxyContin ER 2X day and 20mg Oxycodone up to 3x a day PRN. I’ve built enormous resistance over 15  years of increasing dosages. I’m 65 yrs old.
I’d like to stop as it’s become hard to manage and I know it’s bad for me. I still have searing pain if I let it wear off for a few hours. 
I’ve had 5 back surgeries with hardware and free fragments in my spine. Surgeons have turned me away due to scar tissue and arthritis. 
I had a bout with liver cancer in 2016, so stage 4 cirrhosis. 
I’m in Key Largo for the winter so near Naples. Can ANR help me?
