Anything over 15 mg of abilify makes me so out of it (drowsy) that I can't function. I'm nodding off every 5 minutes no matter where I am, sitting up right, laying down, you name it. I take my 15 mg of abilify at night because it does tend to make me just a little bit drowsy, but it's much better than taking it during the day,

I've never taken lithium so I can't comment on that, but abilify has helped me for a long time.
