For me, with meds:

I like my child (I always loved him--but I now really really like him)
A fight doesn't erupt every other second
He doesn't break everything from numerous window panes and games, toys, lamps, etc. by accident anymore
All his clothes are no longer chewed to pieces
My good friend no longer calls him "pig pen", although he still wears his lunch sometimes.
I'm not afraid to leave him alone with his brother for half an hr while I blog
