I'm very sorry to hear that. Do the docs think she will come back when they can reduce the medication? My father (92, in a nursing home) broke his hip on Christmas Day and was for a while on morphine, after the operation they gave him on Boxing Day. He's off it now but still, I think, groggier than before. However friend Bowser has either gone bonkers or is pretending to have done. (I think I saw something suggesting you incline to the latter interpretation.)
As do I. But in Bowser's case, I consider it self-evident enough (since he pretty much gave us a heads-up a while back ) as to be harmless.
