Good information, thanks for all replies so far. It’s disappointing to hear how quickly this wears off but encouraging to hear of so few side-effects. My dearest is waiting on a new right hip (August, with the left one an estimated eighteen months later) and rips through painkillers - it’s not my preferred MO.

One of the companion issues I’ve apparently got is narrowing of the “bore” in one’s spine such that it slowly constricts the spinal cord over time. Eventually surgery to ream it out, will be required. Hopefully the current condition will taper off with time, injections, gentle exercise and return to near this baseline.
