I have been on and off abilify a few times. At first it pulled me out of a cave and I could live again. Then it wore off in less than a year at many dosages. So I quit. Then went on it again half a year later and it worked again. Then not so I went off. Now I'm on again and it has quelled the internal fighting but for how long. I may have gained a few pounds on it but not nearly like I did with seroquel and risperidone. It's been really helpful, though, but short shelf life for me.
