Olanzapine is a powerful anti-psychotic and sedative medication.  I currently take 10 mg a night for anxiety and agitation, mixed in with some paranoia.  It has helped because I remember the first morning after taking for the first time.  Once the grogginess lifted my mind felt calm and quiet.  It was nice but the badness has started to creep back in, but not as bad as I was. When you take it you get tired and hungry, well I do and have put on weight since taking but I am addressing that issue.  I can’t put up with that compared to how I was before taking olanzapine.
