I was on ability for about 2 weeks to try to help calm my racing thoughts and chill me out on my supposed "mania" (The dr. said I might have a slight mania), at first it helped just a touch, not really much - but then towards the end of the second week, I felt faint and very nearly fainted... also felt like I couldn't concentrate at all. Now, months later, I feel as if it has permanently altered my brain chemistry because where I was almost manic in my energy (which was actually nice sometimes) now i have no energy at all and am sleeping tons and just can't get going in the morning. It's awful. Extreme fatigue that I have never known in my life before. I'm hoping to treat it with vitamins, exercise, sun, and am going to see a Naturopath. I won't touch any brain-altering meds in the future ever again. Abilify is horrific they need to just do away with it.
