My husband has Alzheimers= 6 years in. He was a musician and for stage fright, would have a shot of vodka and a few light beers over the course of a long night. He doesn t play professionally anymore but practices every night. He wants vodka, has 3 regular beers and wants a glass of wine too. I water down the vodka, only give him light beer. His behavior is awful during this period (sundowners). I am at my wits end. What should i do? Thanks
