So far, my pdocs have lived to switch my meds around, have had no problem overmedicating me. I on the other hand I didn't want this. I didnt mind experimenting to find ones that work, but I think I would be more tempted to replace one with another than to just keep adding to them. If you are overmedicated you might not be able to meet your goals either.

Would he be willing to let you try a different antidepressant perhaps? Or even something other than abilify? I have tried abilify but honestly it didn't do much in terms of stabilization for me at all. My best results have come from lithium, but lithium hasn't been enough to keep mania away, but again antipsychotics haven't, neither have anticonvulsants. I have tried so many AD's only to become manic, mixed or rapid cycle every single time. If I were you I would keep requesting trying something new. It's you who's living with it, and just "meh" isn't that good.
