I am highly unstable since dropping my olanzapine from 30mg to 10mg

Hello,

I am diagnosed with schizoaffective disorder. I complained about the olanzapine weight gain to my psychiatrist and he decided to drop my olanzapine from 30mg to 10mg, saying if I wasn't feeling well I would go back but this time to 20mg. I did that, still felt pretty unstable 2 weeks later when the dose was supposed to calm me down. Called 911 one night because I wasn't okay at all, the doctor from the ER told me to go back to 30mg and to ask my psychiatrist to taper next time. I haven't seen my psychiatrist yet, I will see him very soon.

It's been about a month since I am back on 30mg and I still feel pretty unstable. I have what looks like a manic episode, I sleep 3 or 5 hours a night and wake up refreshed with a lot of projects in mind. Last night I couldn't stop hearing the damn police sirens through my windows only to be told that I was the only one hearing them. It wouldn't stop and it was so freaking loud. Then I would look at my phone every damn minutes because I couldn't stop hearing it ring but no one was calling or sending me texts?

I don't know man, I don't want to live in psychosis while still being on 30mg. It sounds terrifying. I wish I could be normal.
