What dose or abilify are you taking right now? In low doses, 2.5mg it's used as an effective pro dopamindergic add-on to various antidepressants. Above 7.5 mg it's blocking d2 dopamininergic overactivity, thus can be effective for stuttering. I've been takin it in low doses for depression, never felt any fluency improvement. but I've never used doses 10mg and above... This week I will start clomipramine , let's see if it will have impact on my stuttering.
