Yeah, Abilify has been a tremendous help with my depression. I found that out when my psychiatrist agreed that I could try going off it. Bad news!! Abilify is really helping, it turns out. I got back on it fast!
(I'm bipolar II, which may have some impact on how much Abilify affects me, but I understand it is very helpful with unipolar depression too.)
I did take Abilify with Cymbalta for a long time, and they seemed to get along fine. (Cymbalta happens to make me drowsy and lethargic, so I have since switched from that to nortriptyline.)
