Along with allergies. I stopped
oxycontin 40 x 2 / day, + 600 mcg fentanyl
IR, but while still taking opana 10s
IR 2x / day 30 days before my 2nd major neck surgery. I didn't tell the Drs or hospital staff since it was 30+ days ago. Tolerance was still there though. I awoke in severe uncontrolled pain after surgery, they assumed I was faking for more meds, until my BP went sky high, nearly coded, and they consulted my wife. She informed them of my prior meds.
