I do not feel the Lithium is the cause, it does not cause anxiety. I've never been prescribed Abilify, but take Lamictal.
I also, in the past had been on (my choosing) Lithobid, for My pdoc and I found Depkote not to agree or address my problem.
Lithium, is an excellent med for BP-I, Lamictal is excellent for BP-II (which I am) but everyone is different so are the meds and effectiveness.
It is important you tell the prescribing pdoc exactly what you are feeling, so med adjustments/changes can be done.
Some of this can be temporary side effects,and some may not, so checking with the pdoc is important.
I've been on Lamictal for about 3yrs or more, 200mgs and have gone to 150mgs, in the past when the pdoc and I were trying 225mgs, the extra 25mgs did produce agitation in me, so we went back to 200mg,even down to 150mgs.
This experience showed my lowest therapeutic dose is 150mgs,dosages above 200mgs were not beneficial.
Feel free to let us know how you do with your pdoc visit,etc.
Take care now,
DE
