Hang in there. Abilify is supposed to help with the hallucinations and disordered thinking. The side effects you mentioned might go away with time. Two weeks is about how long it takes for the drug to reach steady state in your system.

I hope this works for you. The side effects are a nuisance, but hopefully they will subside as you get used to the drug and the benefits will start kicking in. Otherwise you may have to try something else.
I started at 15mgs too, but eventually had to go to 30 to get complete remission of symptoms. I don't have any side effects now except occasional blurred vision, but I can shake that off.
I'm sorry to hear that your having a rough time with side effects. I hope it gets better for you soon!
