90 yr old mother alcoholic. Mom lives in a senior facility- not assisted living. My sister and I visit daily and buy her personal needs. Mom has always had a glass of Brandy as a night cap of which dr approved. However- to make a long story short- mom started losing weight, complaining of memory loss. After a clean bill of health and a family meeting we realized she was using several family members and friends to purchase brandy. Good lord- we realized she's consuming a lot. I was elected the "voice" and confront a mom. We had an awesome conversation- so I thought. I just need some feedback- She is mentally competent but I don't want to enable. Do I take the chance she gets angry and finds a friend to buy anyway- or keep my mouth shut? At this point I fear she may fall and since I have the medical poa- could I be liable for her poor choice?
