I've never been on Abilify, but I'm on Lamotrigine (Lamictal) and for me it makes my head clearer and helps me concentrate better...maybe it is a side-effect that will pass? If not, I hope that you and your doc can find an alternative. Good luck!

You live with the threat, you tell me you live with the threat of my extinction. Leonard, I live with it too."
