I've been dealing with this for months and she was doing fine on Ambien and then all of a sudden started hallucinating at night. Before the Ambien I was using a combo of herbs to include melatonin. So I've gone back to that in higher doses but then all of a sudden they won't work either. I've tried 50mg of Trazodone which didn't work so gave her another half and it sort of worked. She is sensitive to drugs - she either has a horrible reaction or needs a lot of it to work. She cannot tolerate most anti-depressants or any drug of that class. She only takes a blood pressure medication and carbi/levodopa and supplements. Someone recommended seroquel but I am concerned about the drugs because she doesn't tolerate them very well for very long. I can't be up all night like this 3 or 4 times a week.
