Rescue person mode kicked in - I do NOT mean to offend anyone and its only what I've found, but:
Don't worry.
If she's not a rail, if she's still got good weight on her tail and legs, and she's still fighting, she'll be fine. Its so alarming when animals don't eat, especially for long periods of time, but sometimes the body needs to heal so much that hunger and the energy of digesting food almost disappears. If she was lying limp and listless, rail thin, with hip bones sticking out then yes I'd worry, but it sounds like she's still in good body condition and feeling feisty. Be patient, it'll happen!
When I got Tempest, he was rail thin, but he fought like a champion. He refused to eat for 2 weeks, at which point I started force feeding him mushed up soaked ig pellets. I would pick him up, and when he opened his mouth to bite I'd push a long, thin piece of carrot or bean or pea in there, and he'd chew and swallow, but on his own? Never! It was over a month before he actually ate anything on his own, the whole time I was a nervous, worried wreck to the point my vet was getting peevish with all my calls (he's a saint!). Now he's huge 
If her body condition is good, I'd actually stop with the force feedings until her stitches are out. As long as she's hydrated, she should be fine. Offer food every day, but take it away if she doesn't eat it. If she looks dehydrated, I'd make her drink water, but thats it.
Have you called your vet btw? He might have better insight as well, as he knows Beanie's case. I'd like to know his advice too, its always good to be learning. I know with mammals, a few days off food makes such a huge difference, and as mammals we tend to think in those terms, but reptiles are much different with different tolerences.
