I've been on 2.5 mg per night on abilify for, and I my whole body has spasms/twitches?

How long will this side effect last? I've stopped taking the abilify but it is still twitching, my doctor told me to use akidin to help with the twitching.

What I'm afraid about is that this might become permanent and worse.

Could 2 weeks of abilify really do permanent damage?
