Just like any other medicine- Abilify will have a different effect depending on the person; the episode a person is in, the type of depression a person deals with, or even personality traits.
It definitely can make you drowsy although it may not. As far as giving you energy, I have never seen that happen. If it works in conjunction with whatever else you take or do for your depression than energy will come but I have never personally seen it happen to where I could say that the level of energy went up as an immediate effect of the Abilify.
We don't all have the dame chemical imbalances or mental ailments.. for example, a person with ADHD uses Adderall to calm down where as college students without ADHD use it for speed - to keep them focused. Or in my experience.. I have watched people take benzos & nod out, while I actually needed them & they gave me energy making me talk alot lol. Medications are different for everyone.
