I switched from zyprexa to abilify due to weight gain. And I have to say, at least for me zyprexa worked better. I believe zyprexa is stronger judging from my expeirience. If it were not for weight gain I would have stayed on it. Abilify does nothing for me sleep wise and as far as psychosis or delusional thinking abilify isn't working as well.

Why does she want you to switch?
