That is a tough call. IP can be very helpful, but there are also cases in which it is a mess.
Is there any chance your therapist could call your pdoc and request an earlier appointment? If you've given the Geodon time and it isn't working he should be informed. Maybe one more adjustment could work?
If you do go IP, call them first and ask about your options for checking yourself in. That is a better process usually than being committed and transfered from an ER. My IP had a special unit for women in trauma situations. You can request services like that sometimes if you go in on your own. Also, maybe your pdoc or therapist could call ahead on your behalf and provide background.
As for the drugs, that depends. They monitor you closely and make adjustments as needed. Some doctors are more heavy handed than others. The best thing you can do is be as honest as possible in your doctor visits and group sessions while there. It gives the treatment teams as much information as possible, and the more info they have to work with, the better.
Take comfy and warm clothes. Nothing with strings. I was freezing the entire time.
I hope you are able to get the help you need.
