Alright, an update: I've been taking 5 mg less of zyprexa for almost a week now. I'm doing well; a little shaky, but mostly okay. I'm still having a hard time waking up, and go through hungry spells where I want to eat everything in sight, but I suppose these side effects won't stop until I'm completely off the meds.

The biggest thing I've noticed is changes in my motivation. Instead of being mildly motivated most of the time, on the lower dose of the zyprexa I go through periods of intense motivation (still nowhere close to mania, though) and periods where all I want to do is lie in bed and sleep.
