He sleeps very badly, that's common with Alzheimers. He gets up in the night, at which point he will get himself a drink and he sleeps quite a bit during the day. We know that some exercise will help him sleep but getting him to do it is a battle, and we're only talking about a short walk not aerobics!. We have tried using fully skimmed milk which obviously reduces the sugar, he usually has it with coffee or Barleycup but makes it with all milk and no water. If my Mum makes it she uses half milk half water. Soya would be a problem as it tends to curdle with coffee, I also don't think he'd like the taste, however I might try some of the other types of milk, maybe he'll like one of them.
I think the old "milk is good for you message" is part of the problem, milk was always seen as being natural and wholesome, which it is, just not in those amounts!
The big problem we have in trying to tackle any of the problems is that not only does he not understand any of it but because his memory is bad he doesn't accept many of the problems he has. If we say that going for a walk will help him sleep he won't accept that he has a problem with sleep, he might remember that sometimes he gets up in the night, and sometimes he has a nap in the day, but he has no idea that he can wake several times in the night to the point where he is getting up or that he can fall asleep whilst you're talking to him or sleep for most of the day. The same process applies to any of the other problems and there are currently rather a lot of problems.
Thanks for all the help. Northerner , putting it in terms of a Mars bar really puts it into perspective.
