I wouldn't jump to clorazil until you've tried all other APs. It's a serious drug. It causes more severe weight gain than Zyprexa! It is usually used as a last resort in severe, treatment resistant schizophrenia; not sure why your pdoc is bringing it up when you have so many other options...

Hopefully IOP will help. I've never done an IOP program before, but from what I've heard about them, you get a lot of care. I think it is like IP, but you go home at night. Do you feel like you can keep yourself safe? If you do, then IOP is probably a good option to get your symptoms under control for now. If you're feeling like you are in danger, then you probably should push for inpatient treatment.

I hope you find some peace soon. Don't hesitate to call your pdoc if it gets to be too much. He gave you his number for a reason.
