Hm. I wonder if it's the Abilify?

Or, it could possibly be the Prozac, even if you think it's not likely. For example, maybe you took Prozac before while on Lamictal and Lamictal did a good job of preventing agitation caused by Prozac. Then when you went off Prozac and started it with Abilify, maybe Abilify isn't able to prevent the agitation from Prozac. See what I mean? (Sorry if my wording is poor.)

I hope you're able to talk to your pdoc about this soon.
