After listening to the show Wednesday, I am thinking that Robin may be addicted to some pain killers. Wednesday she was particularly aggressive and irrational. Vicodin does that to me when I take it. And Robin has been acting like this at least once a week since she has been at home lounging around. Of course Howard won't notice it until she is in rehab. And Robin is such a narcissist that she will never admit that she is addicted to anything.
