My FIL whom has been living with us for 13 months cannot get more than 3-4 hrs sleep even with a couple of perscription sleeping pills. This has been going on for a month now off and on. And today as I prepared for work, he came in convinced it was Saturday--I had to tell him 3 times and finally show him the date on the TV. He is a big man, overweight/Diabetic/heart issues/bad circ im legs/begining Althymers and diamentia (Excuse the spelling). I believe this is a sign of progression. Please let me know if my gut is telling the truth here?
