"been on abilify for 4 months and had to go off.  it&#039;s a great medicine for bipolar.  i could tell when i missed a dose because i would flip out.  the down fall on why i went off was the weight gain.  i gained 30 pounds in 3 months with just snacking.  dr told me it slows the metabolism down.  i think it stopped it.  so give it a try."
