Has anyone taken escitalopram (generic Lexapro) and Abilify together for anxiety disorder, depression, and slight bipolar disorder?

I've been on escitalopram for years for anxiety/panic attacks and for the first time saw a psychiatrist today. (I got tired of seeing my primary care doctor for medications; felt like I should see someone that is a bit more trained in this area of drugs).

Anyway, the psychiatrist didn't change my escitalopram (20mg) but added abilify to it and said I should take a quarter of a 2mg tablet for a few days, then half a tablet etc to ease myself in to it. I also take 1mg of generic ativan in the morning.

Has anyone taken this combination of drugs before? I'm curious as to what to expect. I think for myself, my main concern as always is not wanting the new drug to make me have a panic attack! (Those of you with GAD know what I'm talking about.)
