Don't worry about the zyprexa right now. I was put on it and worried about weight gain; If you exerecise it won't be a huge problem. For the moment, though, you're in the hospital so do what needs doing. I've never been inpatient, but been to PER several times. So yeah- just do what needs doing in the hospital to get better. And besides- I have felt SO much better on zyprexa.
