Sango never actually 'looses her mind'. she gets completely distraught during episode 50, that unforgettable face, over her brother Kohaku and almost commits homicide/suicide over him, then in 100, fight in the forest of despair, where she was in the coccoon of the moth demon, and saw an illusion of kohaku killing her friends (not real!). Finally, sango gets drunk on the mist of sages, as it is what appears to be sake in gas form. She then attempts to kiss InuYasha, and leave the others behind, then finnaly beat the snot out of miroku in episode 135, the last banquet of miroku's master.
