For anyone who hallucinates and has taken APs for it, does your hallucinations ever get worse when you've just started taking an AP?

I just started my Zyprexa and Bupropion a few days ago and I'm still trying to adjust to them. This isn't the first time I've started Zyprexa and had worsened hallucinations and paranoia. It never lasts more than two weeks, by then everything calms down or completely disappear.

Anyone else have this experience?
