I was a heroin addict for many years and also have chronic pain and mental illness. When give OxyContin or oxycodone or the such in the early years I abused the hell out of it. My psychiatrist talked with my pain doctor and decided on long term pain patches such as duragesic. The idea behind it is you where the patch and change t every 72 hours but you don't have a bottle of pills you can overtake or abuse. This may not work for everyone but it did work for me so just a suggestion. It does get easier with time. Good luck.
