I started with 2.5, then 5mg, now 10mg. It's affect wears off with me every few months and I'm not sure raising the dose does anything but I do it anyway. No pdoc around these parts so I just do it myself with the drugs I have left and cut them up. I do find the affect of abilify wears off for me in a few months and then doesn't work at all. I've been on and off a few times over the years and if I go off it it works again next time I take it for awhile. It's been a lifesaver at times but poops out regularly for me.
