I've been on Abilify for several months and also had sleep issues when beginning it and again recently when my pdoc doubled my dose.
While my pdoc suggested taking it at bedtime as it could be sedating, it has never sedated me in any way and I had to switch it to mornings. I still had a couple of weeks where I slept almost not at all, but that does pass in time. I found that Seroquel helped me immensely. I don't know if you take anything for sleep but that may be something you could discuss with you doc. I take a very small dose, (25mg) and it is quite effective.
This will pass, hang in there, I've found that Abilify is one of the few meds that works for me and as an added bonus, I've lost 38 pounds. Back to my old weight. I"m not sure if that was all the abilify or if the wellbutrin played a role in that as well though.
