Olanzapine also called or generic for Zyprexa, is classed as an anti psychotic drug which is widely used to also treat bipolar. It clears up thinking rather dramatically, and best of all within the hour. For myself, it means breaking the cycle pre crescendo, as it were. I still cycle and all that, but when the pit of hell is yawning and all the "features" are in bloom, I can bring that tension to a screeching halt. And I can do that without having to stay on it. If you stay on it, there are some weight gain symptoms and such, just like any of them. I choose to deal with most of what happens pretty philosophically and live simply enough to be able to, but when it's bad, that's what I know to do. I'm sure it's different for everyone, but it's such a dramatic experience for me, I can get pretty exuberant in recommending it. There is a very good link to information on it at the top of this page. Click on meds, find olanzapine in the list and click on it. It was so good for me i was surprised it took years to find it.
