I weaned myself off clozapine a couple months ago. I just went down 25mg every third day..which is kinda fast but I didn't have any rebound effects. I had a bit more anxiety but that's it. I suggest having your pdoc on board but I understand the urgency. I was on another ap when i went off of it, so that might be why it was a pretty smooth withdraw. If you stop cold turkey and don't have another ap on board you could become psychotic. Be careful.
