My Mother, who is 82, has Dementia and enjoys her wine to the point that it is a problem and I am quite frankly over it! She gets very demanding about having her drinks in the evening. If I left it in the house during the day, she would start earlier, and has done this on occasion when I forgot about it being in the refrigerator. She doesn't have access to transportation and is probably just bored. This is her enjoyment. Drinking and Dementia do not mix well. How can I help her to understand that the wine is not helping her without causing increased tension?
If I were in your shoes, I would consult with a medical professional who has experience in safe withdrawal.
