Watching Monk. In this episode- Mr. Monk Takes His Medicine- Monk is given a prescription by his psychiatrist and turns into the complete opposite of his usual self. He doesn't care if things aren't tidy and he bought a fancy convertible and is bopping down the street in it. Everything tastes great to him and nothing bothers him. Seems to me that Monk had a manic episode brought on by the med.

Just thought it was interesting. No doubt, he will "go back to normal" by the end of the episode.
