This has been a lifelong pattern for him but now, it is wearing my mother (who has dementia) and myself out. He wakes up about 6pm and stays up until 5 or 6am. He rummages through things and tries to find his things all night. Should we try to change this lifelong habit or just go with it? If we go with it, what time should his sleeping pill be taken? Right now it is taken around 7pm and doesn't work until 5 or 6am. Any ideas? He INSISTS on getting a sleeping pill every night. Help!
