I Am In Pain Management. I Have Taken High Levels

I am in pain management. I have taken high levels of morphine for over 4 years now. I am looking for a non opiode pain medication as alternative to the morphine. I cannot take gabapentin and Ive had trouble taking lyrica. Is there an effective non narcotic pain alternative that doesn't have a history of bad side effects and which is effective in the control of pain today on the market
