to Sara: Your father's camel hallucinations do sound interesting! My own mother decided to sleep in another room after the night Dad knocked a hole in the wall thinking he was kicking an enemy soldier (he's a WWII veteran)--and this was years before he was diagnosed with PD. And you're quite correct -- life ain't worth living if MOM CAN"T SLEEP! I wish luck and love to you and your family. manderwiz aka joyce saylor
