thank you. you helped me alot. i wish you and your family a very happy healthful new year.
First of all... take a deep breath and calm down.
Secondly, 70% kidney function in an 82 year old is pretty good! I've got 60% in my left kidney and 70% in my right, and I'm only 39, and my prognosis is a long and happy life, as long as I watch what I drink and stick to my medication regime.
As for the Xanax, only she can know whether or not she's going to get 'addicted'. Remember, being "med dependent" and being "addicted" are 2 completely different things. She's 82 years old... I'd cut her some slack. If it makes her comfortable, I don't see any harm in letting her have a Xanax now and then.
Good luck!
