I also tried 10-15 antipsychotics, including Clozapine, before settling on a combination that neutralized my symptoms.
I am on Abilify 30 mgs and Geodon 20 mgs twice a day.
I took 800 mgs of Clozapine on monotherapy. It worked partially. Then I mixed Abilify with Clozapine. It worked 99 percent. But, I was having terrible side effects. So, eventually, I ended up on the current combination with no symptoms.
As for Clozapine it is very heavy on side effects.
