I know how badly you want to see her eating again, but it's likely that she needs a few days at least to rest & rehydrate, especially since she was thin to start with (according to your description). Wait until you see some interest in food. Otherwise you'll likely be wasting your effort & the prey. A dehydrated snake may have trouble digesting & may barf it up, making things worse, since then you have to wait longer (a few weeks) before feeding, to give them time to replenish their digestive enzymes. Patience...
