Pain Dr wants 2 change my 5/325 Vicodin,4-6hrs, to moriphine or methadone. I've been on same dose of vicodin for 6yrs. No increases. My liver/kidneys are tested good. I've researched these other drugs, they scare me. Socially not accepted. I've managed well. He even says the same. What do U think? Dangers+positives if there R any? Is this some fashion trend; soup of the day? WORRIED. Quaily of functioning life is vital to me. Can he force the change? I'm on medicare, retired.
