I had a problem a few weeks or so into my abilify. I noticed that I couldn't walk as fast on the treadmill, nor could I walk as far as I usually do, and I couldn't seem to stop munching on snacks. It was driving me nuts!
I told my pDoc about the problem & he decided to take me down to taking it every other day, then twice per week. Abilify has a very long half-life. I've been on the 5 mg/s twice per week for a year or so now. And those horrible side effects have gone away for me, thankfully.
