Katie - I'm so happy that your hubby will be doing the "heavy" work in straightening up, and I'm confident that he will put a halt to any involvement on your part that would put you into the ODIC again.
I had general anesthesia last year for my surgery, and this year for my TKR I had spinal anesthesia, general anesthesia, and a femoral nerve block. I knew prior to going under that all three were being administered. The anesthesiologists had a copy of my pharmacogenomics tests (Rx DNA) and noted the yellow box warnings that I have extremely low sensitivity to pain meds and fentanyl, etal. The day I was discharged someone from anesthesiology came and pulled out the nerve block wires that had been hidden under layers of batting covering me from hip to bottom of my foot. The only adverse reaction I had was weeks later when I saw the $23,000+ pharmacy bill from the hospital, including a very long page of itemized units administered during the surgery on May 28th.
