The new "Oxycontin" Formula is giving me headaches and not working well at all. I have been taking a total of 150mg a day of "Oxycontin" for almost three years after a bad car accident. It allows me to get up and run my business, a life saver. I am considering a change to Hydromorphone ER, but I don't know what the conversion would be? Any information or link to a website that has this information would be appreciated... Thanks
