What is wrong with Randy Quaid - psychologically?

My opinion is that he may be a bit off, but he most likely engages in drugs and alcohol. Both drastically alter a person's state of mind. Also, I think his wife is the really crazy one. There is no doubt that she is completely nuts. It is rumored that she does drugs, too. I think he tries to keep her happy, also, and that she wears the pants of the marriage. I did a little research for you, but I couldn't find any real source that states that he has any specific disorders. I did find an article on their rumored drug use, though.
