I heard Abilify actually takes 2-4 weeks or potentially even months before it reaches its full effect. I am also trialing Abilify currently taking 2mg as well. Been taking it for a week and main side effect is that I feel more tired? or just sedated? I wouldn't say its too bad but in terms of speech I do feel it has helped quite a bit (maybe like 50% reduction in blockages and repetitions?)...perhaps because I am forced to talk slower now and don't get anxious as easily. I will keep trialing it long term to see if it actually works.
