I take Norco for Degenrative Disk Disorder and Fibromyalgia. Watson changed it from a yellow pill to white. It is not effective for pain at all. I know my tolerence is not up. I have seen many other people saying the same thing. Is this a stunt to keep people who don't need it from getting addicted or what? I am thinking about changing to something else. I see a NP overseen by a Physician. Can you shed some light on this? Thank you very much
