I take rexulti which is similar to abilify. I believe it’s a newer version? Anyways I tried abilify first but it made me restless. It did help with anxiety/depression but not stuttering. Would have stayed on it except for the restlessness. Rexulti works the same for anxiety and depression but no help with the stuttering. There’s no real harm in trying it. If you don’t like how it makes you feel you can just stop taking it especially if you haven’t been in it long
