I have a person with Parkinsons here. He does not sleep at night. He takes ambien, that we know not good for Parkinsons. He is sleep walking, it is a torture every night. I think and I did a research, ambien makes Parkinsons worse. Does anybody knows what to do? Please if you know anything. He tried relaxium and all others advertised on TV (shame on him). But when you are desperate, you try anything. Is there a good solution to this? Please help
