Zyprexa and Seroquel vs. Abilify

[ahalo]

I know all these meds (Zyprexa, Seroquel, Abilify) are the same type of medication, but how do they compare with one another in terms of effectiveness and reactions of patients?  Apparently my mom has taken both Zyprexa and Seroquel and had awful reactions.  Seroquel in particular made her very active and loopy. 

I'm just wondering because I've taken very low doses of Abilify and have noticed no change in my behavior or actions, but it seems to help with my anxiety for some reason.  Is that normal, at a low dose (2.5mg)?  It helps me sleep better as well.  I decided to add it to my low Effexor dose 37.5 mg because I was starting to feel anxious.  I've noticed that ever since I've taken Abilify the Effexor doesn't seem to make me as tired.  So either that's a coincidence or the Abilify is making a difference.

But I am a little leary of increasing the dose because I'm worried I might have a similar reaction to Abilify as my mom had to Zyprexa and Seroquel.
