I too became manic on the Abilify. Very shaky, very irritable, just not very pleasant at all. As soon as I told psychiatrist how i felt he immediately switched me to something different. Alot of the atypicals are chemically similar, but everyone's bodies are different and what works for one might not for another. The Abilify was my worst nightmare. Risperdal did nothing. But Zyprexa and Seroquel were wonder drugs for me...first med I had ever taken for bipolar that I actually felt it worked. All these drugs I tried were very similar in chemical structure, but I responded differently to each one. The side effects such as huge weight gain and elevated cholesterol levels caused me to be taken off of both Seroquel and Zyprexa. I am now on Invega, which is a reformulation of the old Risperdal, along with 800mg of Trileptal (an anticonvulsant). Less side effects and it actually works for me, unlike the old Risperdal, although not as well as the Zyprexa/Seroquel.
I guess my point here is that if something doesn't work or makes you feel worse, don't hesitate to let your doc know and get switched to something different. It is not uncommon for people to have to try multiple medications before they find the one that is finally the best fit. And sometimes it is also a matter of not only finding the best one, but the best combo of ones. This can take time but don't give up! It can be a long journey but with persistence and a really good doc you will get there! Good luck!
