I was on herion,then oxycontin for about 12 years. The last 3 or 4 years my use was approx.320 - 360 mg of oxycodone. I paid 5000 dollars for sub u tex treatment , and had a terrible withdrawal. I did stick it out ,but after 5 months I still did not feel even close to my self. I started using again. I got into treratment and put on suboxen. Itruly feel i may have to take something the rest of my life!? Wondering if methodone would be a better option for long term? Your thoughts please
