Hi ... I hope your wife feels better soon! It must've been scary for you, as well.
You ask specific questions about bipolar, so I hope that people who can answer you questions see your post. Otherwise, there is the bipolar section of this forum.
I have major depression with psychotic features and the Zypreza 10 mg I took was pretty fast acting, plus also feeling safe in the hospital helped me. I eventually had other meds added to my regimen for me to stabilize and become functional which took some time and had some ups and downs.
