Without getting too much into my story(which would be rude), the short answer is yes, and despite my objections, I was on thirty or thirty two mg. It is a lot and I experienced the extreme fatigue you speak of. Mine was terrible and I couldn't sit comfortably, even, for about one month. Though I was eventually placed on provigil, a cns stimulant (non narcotic) to mitigate the fatigue, I do know that after about a month it let up a bit. A word of caution, however, is that there is tardive dyskinesia associated with aripiprazole, so if people around you start saying things like 'why are you making that face/similar movement you are unaware of?'
Discuss it with your doctor at once. I took it about a decade ago and to this day have an uncontrollable hideous facial expression that is always bound to be photographed!
