Absolutely YES. That's too much de-titration too fast on that particular med for most pts. I'll throw a Jackson on the table for withdrawal effects.
No big surprise there. (It's nature of that molecule.) Latuda is still expensive (though heading toward generic status in what, two years?) but may provide the prop under the autonomic downforce typical of most Da-blocking anti-Ps you need. That said, Cloz is a really dandy med if you can handle the long list of prominent sfx.
I would suggest moving back up to 200 mgs to see if you get some relief from the anxiety at that level. And try your best not to use benzodiapzepines (like Ativan lorazepam or Klonopin clonazepam) for the anxiety unless you just have to because of the sine waves they set off that will induce more withdrawal effects with continued use. Likewise, try to stay off caffeine, chocolate, alcohol and sleeping aids other than melatonin... as those also have potential to induce rebound effects.
