You must wait MUCH longer between regurg than two days. If not you have another regurg

The snake needs time to recoup digestive liquids in the stomach and relax before it can hold another meal down.
In this situation I would let the snake rest for at LEAST ten days. No feeding attempts, no cleaning, nothing. Make sure the hot spot is nice a warm, maybe even a smidge warmer than normal.
After ten days-two weeks try a smaller tha normal prey item. IE.. if your snake is eating small adult mice, offer a fuzzy instead. Keep the snake eating smaller meals for a few succesful kept down feedings then you should be safe to move back up.
