We are living the same nightmare. My mother is 78 and on Endone, Oxycontin, Valium and a cocktail of other drugs to deal with chronic pain as a result of years of operations for hip and knee replacements. She is also no longer the Mother we know and love. She has become angry and paranoid, at times delusional, self pitying, agressive and unable to do anything for herself. My Father is also broken and unable to cope anymore. I completely believe that it is the drugs that has made her this way and we are desperately trying to find anyone who specialises in a multi pronged treatment plan. But everywhere we turn the answer seems to be to put her in a nursing home. I know my Mum is still in there somewhere, she just needs the right care to find her, but noone seems to offer it.
