There is no such thing as a "normal" regurge. If a regurge happens something is wrong. Environment, handling, parasites....something. I've kept reptiles for about 13 years now and its been a rare occurance even with WC animals.

I'd take the snake to a vet and get it checked out. Once an animal is regurging it usually takes some work to fix the situation.
