I am a long % year history of morphine ER . Starting 30mg and escalating to 180 mgs daily. Due to 11 reconstructive surgeries over the last 15 years. last 5 years awaiting a right complete knee replacement. It was successful and the added Oxy IR 30mgs 2-3 times a day, for post operative pain it works well. The Morphine ER was planned to be reduced as to it has become non necessary now . In fact is causing diminished breathing issues. it has been reduced by me over the last 2 months to a from 180 mg to even 45 mg. however even that is causing extreme breathing and anxiety stress. I have stopped it the last 4 days completely! i am feeling better , except the with drawl symptoms. extremely lathargic, sinus issues, muscle twitching and severely depressed already and edgy. I go to my pain management tomorrow morning. I need to have and have heard there some standard medications to be used with withdrawl issues non-narcotic preferred. My pain has been managed almost completely at least functional and able to make a good physical recovery as expected. with the Oxycodone IR 15-30mg tabs 3 times or less as needed for pain. do you have any recommendations?
