Hi Bern
I'm so sorry to hear of your wife's illness & the problems it is causing.
This wanting to go home is a very frequently-reported state of mind here on Talking Point (TP), & must be so frustrating and infuriating.
There's another recent thread here (
http://forum.alzheimers.org.uk/showthread.php?t=24623) which is only one of literally hundreds I've read over the years.
Sometimes going out for a short ride round in the car & then "Here we are, home sweet home" can work, but even if it does it would not be too convenient at 00.33 or whatever.
For some it's a passing phase, others maintain it for years, & some people exhibit this particular confusion only during 'Sundowning'.
I hope Talking Point can help you cope (on the principle of 'know your enemy', by reading the experiences of others) & give you a place to express your concerns & exasperation!
May I ask, do you have any family nearby to support you?
Best wishes
