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
In my opinion he needs to be detailed cognitive function test and detailed blood analysis like thyroid, hemoglobin also check blood serum b12 levels also give thiamine supplements ant cholinesterase inhibitors like done pill.  Along with that short term use of low dose antipsychotics like olanzapine
