Anyone haveing trouble with the new Oxycontin formula? Real Pain Patients Only!!!!?

I am a chronic pain patient and have been taking Oxycontin for around 4 years now, it has worked better with less side effects than anything else around. However, this new version that has just been released by perdue is making me miserable. I stopped taking it and have only been taking my breakthrough meds since I got it. It makes me burn and itch all over my body, and doesnt seem to work as well for pain as the old stuff. Just wondering if anyone else is having similar problems?
