Might be easier if she switches to a different benzodiazepine first.
Could be. But we have all pretty much given up on trying to persuade her to do anything. When a responsible MD suggested that the Xanax was doing her no good, and recommended different medication, she got belligerent and refused to see him again. 2 docs later she found one that gives her the stuff.
She’s a lost cause. I just wish she was located much further away from us than she is now. Sounds cold, but after 30+ years of her, I have no more sympathy.
