Sometimes I do feel blunted or numb, but I haven't been able to link it specifically to Abilify. (I am also on several other drugs.)

I tried to go off Abilify recently, and I felt no improvement in emotional responsiveness. Instead, I just felt awful and unstable, with a lot of suicidal thinking. I am back on it now!

What other meds are you taking? For example, I did feel less blunted, and generally more awake, after stopping Cymbalta.

As deliquesce said, do check with your doc.
