I read a book once about actress Patty Duke....an autobiography. She talks about her own fight with manic-depression and tells a GREAT story in her book about how one night someone tried to break into her home. Upon seeing this, she screamed LOUDLY and her teenage sons came running immediately asking what was wrong and why she was screaming. When she told them that she had seen someone trying to break in they replied "Thank God! We thought you forgot to take your lithium!"

According to her this is a true story.
