If Z is making you a bit to flat you can always decrease your dose a bit or go every other day. Half life being what it is.

Lamictal is often a good counter balance if AAP's or AP's are bringing you down a bit to low and its effecting your ability to go about the basics of daily life. It works basically just on the depressive side of Bipolar. Sure there is the "omg dreaded chance of SJS But its less than 4% chance, and caught early people have no major problems)

Abilify it seems causes more Akathesia than some of the other AP'S and AAP's (or at least I read alot of problems about it here) Akathesia seems to always hit at night on a weekend and there is no option but the ER and that typically isnt very helpful, As most ER doctors think Psych patients are making a mountain out of a mole hill at 3 am literally trying to climb up the wall and dangle there shaking like a bad horror story. Best to get a co scrip for Cogentin in case.

I'm not really understandig why your Pdoc isn't thinking " Mood stabilizer" as thats "usually" what is needed for Bipolar Managment in the long run. But most people present a total mess in the office and the first thought is slap them hard with a AP or AAP to get them out of immediate danger then tweek things down the road. but that can often lead to having med after med layered on each other.

Hope you find a good solution
