I too have schizoaffective bi-polar disorder. I have been taking Saphris after coming off Abilify as in your case. I have been taking Saphris for more than eight months now and have never felt better. While it does taste nasty and puts you to sleep rather quickly, the benefits have been worth it. I cannot stress enough how much my mood, sleep pattern, and energy levels have improved since being on Saphris.
I hope it helps you as much as it has helped me.
