Hello! Everyone experiences bipolar a different way, but I can try and help. I can't answer your Zyprexa questions because I'm not too familiar with that med (I was only on it for like a month twenty years ago or so. I just remember it making me gain a TON of weight), but I'll try and answer your other questions.
For me my delusions go away completely and my hypo/manic episodes are not always followed by an episode of depression. It just depends on my life circumstances.
I hope your wife feels better soon!
