Tylenol?

I saw this yesterday.  Tylenol can affect your mood.  Researchers at Ohio State University found that Tylenol and "blunt emotions and even reduce the degree of positive and negative feelings."  I don't know about you, but the fact that Tylenol has any effect on my feelings at all just makes me kind of uncomfortable.  I think I will lay off the Tylenol.  What do you think?
