I know that everyone has different affects with ssri's, but I was just curious as to if anyone else has taken viibryd for depression/anxiety?

I've been on Prozax, Zoloft, Cymbalta and Celexa. All of them in one way or another affected my sleep (either tired all the time, or could not sleep), my sex drive (especially cymbalta, celexa and prozac), 3 of them affected me enjoying anything (like not enjoying socializing, dating people, hobbies, etc), and then also just increasing lengths and instances of my depression. My psychiatrist told me that he hasn't had a lot of luck prescribing viibryd because insurance companies do not like to cover it (mine made me try and fail an additional ssri to get a script to it) so he's curious to see if it will work for me. 
I'm hoping it won't kill my sex drive, but I'm really worried about it actually just worsening my depression. Any thoughts?
