Wow. I don't understand doctors reticence to help you with tapering off the pain med.
I am sorry you've had a negative experience with pain meds.
I have had a good experience. I had tried many different pain meds and chose one that was effective, but not mind-altering for me. I have stayed with low doses, augmenting with other types of meds (adding an anti-inflammatory or a topical, etc.)
the withdrawals can be tough. I get very sick within 4-6 hours if I have missed a dose.
Take it slowly.
