Has anyone else lost libido from using Yaz?

I started taking Yaz about a month ago. I started a new pill pack yesterday, well I have no drive at all. Everything else about Yaz is great! My acne is steadily clearing up and the one period I have had since I have been on the pill was a breeze. Like I said, the only problem is that I am NEVER horny. Any one else feel this way?
