Well, it's 1AM, and my mom woke me up just as I fell asleep, and I spent the last 20 minutes telling her where she is, who I am, and that there are people there to take care of her. The "Who are you?" is always a bit weird when she calls me, and addresses me by my name, but dementia is a thing you just have to learn to deal with.
I couldn't go back to sleep, and was hungry, so had some sliced steak, with Swiss cheese and Cajun mustard on a toasted roll. Will that help? Probably not. Protein and carbs? The only thing that might help is the cheese... dairy.
