I had a similar problem with Abilify. It made my heart race and I was all shaky and in the midst of a mostly manic mixed episode. I also was still having invasive thoughts. So basically, not only was it not doing what it was supposed to do, it was also causing new bad physical symptoms. A bit like what Effexor did to me.

When I told my p-doc, she said to come off of it and we tried a new atypical. That one also had bad side effects, but we eventually found one that still has problems, but is actually getting rid of my symptoms.

The doctor will not condemn you for telling him/her about bad side effects. He/she may tell you to lower your dose (as you already have) or take you off of it completely. Either way, you win.
