Aripiprazole side effects?

I've now been taking Aripiprazole for the last two weeks.  I have found it to have a beneficial effect on the symptoms it was prescribed for but I have also had a few new symptoms that I'm not sure are side effects or not.  Firstly, I have been extremely dizzy and keep getting dizzy spells or spells where I feel completely detached from the world.  I woke up this morning and felt as though I'd been spinning on the spot for half an hour.  I am also getting some random jerking and a tremor.  The tremor isn't continuous though.  When I've had this with previous antipsychotics it's been continual.  I have also been getting some of the symptoms I used to get with a migraine but without the pain although some of these preceeded the Abilify prescription - my voice sounds wrong, I say the wrong words, sometimes I seem to forget everything half way through doing it and it's obvious to other people and now the sizes of things are becoming distorted.   My hands look huge as I type.  Sometimes everything looks huge and I feel like I've shrunk.  

Do you think any of these things require attention and could they be caused by the  drugs I'm on or could I get anything to help with them?  Things only seemed to start when my lithium prescription was increased before Christmas.
