Sometimes they just refuse to eat regularly on F/T. At some point you may have to come to terms with the fact that she's gonna' be a live eater.

And trust me, I feel ya' on this one. I'm a firm believer in the benefits of F/T, but I have one right now that is showing all the signs of being a live only eater. I'm not happy about that, but I will do what's in the snake's best interest, even if that mean's feeding it live.
