Olanzapine
"This medicine is very powerful and is easily the best medicine that I've taken for borderline personality disorder.  If you go down the list of symptoms for BPD this medicine basically takes care of all of them, with two major side effects: sleepiness and weight gain.  I have tried almost all of the SSRI's and SNRI's, Wellbutrin, Saphris and Abilify and nothing works as good or as quickly as Zyprexa."
