Yes, after a regurge a snake needs time to replenish digestive enzymes...if they take another meal too soon, this is what happens...yet another regurge.

Meanwhile get Bene-Bac or NutriBac for snakes/reptiles to use on next meal. These are probiotics...they help to replenish their essential gut bacteria for digestion.

Snakes can die from subsequent regurges, due to dehydration; make sure you keep her hydrated by encouraging her to drink water & keeping up humidity in cage.
You shouldn't offer any food for at least 2-3 weeks, another reason she needs hydration ongoing...& when you do re-offer, it should be even smaller prey.

No way to know if this is "just" stress or serious illness...only time & vet will tell, but probably too soon for a vet visit. Crossing my fingers for you & your snake.
