Thinking of you Macbeth -- I'm sorry I don't have anything to share or answers to your questions and know this must be very frightening. Trying to do the best we can in the deep of night can be very lonely and takes a lot of courage. The mix of medications that can be prescribed for our loved ones symptoms is very confusing -- it sounds like there are major changes going on with your husband's meds -- I do hope you have an experienced physician / home health nurse working with you and responding to your concerns. In the past year, my husband has had several different meds prescribed -- finally last October he started on a regime that has worked well the past 3 months. But it was only after I finally found a physician who was focused on elderly dementia and was experienced with the potential med interactions that we were successful. Wishing you courage and a few moments today when you can care for yourself too.
