I've been on generic Abilify for over a week now. Initially my hunger increased and I was eating like a horse but now it has subsided. I am sleepy though when I take it. I sleep much more now. I take about 15 mg daily and have been at this dose since starting brand Abilify five years ago. I had taken Abilify for about ten years off and on and when I was off, I was hospitalized. I went off Abilify four times and was hospitalized four times. Now, I take my Abilify daily and have no problems with psychosis or mania. I think the generic Abilify is just as effective as brand Abilify. I am happy.
