YES, Tom(FL) yes! I was reading to the bottom of the earlier post to see if anyone knew the answer, and Tom got it!

BillW, it may be as simple as salt tablets! My mother died last March at 91. She was in a good assisted living unit in central NJ in Lakewood. When we finally figured out it was her low sodium that was making her angry, argumentative, disruptive--it was an easy fix. We are all so brainwashed into watching our salt intake with the thought to decrease it, that it is hard to believe that LOW levels can change brain and behavior. We spoke to her doctor who eventually was persuaded to prescribe 1/day but that wasn't enough to really cure the problem. My sister who lived a few miles from the care unit, bought a bottle of salt tablets at the local pharm in the Shop-Rite. (They non-prescription, over the counter, can be bought anywhere.) If mom was having a 'bad day' she gave her a salt tab. She changed within an hour--it was AMAZING to see. The facility can only give out what the MD orders, but there is no law against giving someone a salt tablet. It changed mom's life from stress and agitation to the calm sweet person she used to be. Not sure if I remember the levels correctly but I think she needed a level of 137 to be normal, and if dropped to 130 the bad times started. Dif people need dif levels. Check on that.

Also a simple sleeping pill like Ambion or same ilk will keep someone asleep 11 PM-7 AM. Yes, eventually they are habit forming, but so what? He is in a facility that has medical oversight and his MD shd prescribe them so he has a quality of life--and so do the people around him!
