I was on it for about a year. I don't have anything bad to say about it except for that it did have a slightly sedating effect for me. I took it at night though before bed and that helped. I would sleep off most of the drowsiness.

I have heard that one of the biggest problems is weight gain. As for the involuntary muscle spasms (tardive dyskinesia), I have heard that they put the warning on Abilify but it's really not too much of a problem as it's one of the newer atypical antipsychotics. Also, believe the side effect is only reported on high doses. But of course, I'm no doctor and you should talk to your pdoc.
