I agree 100 percent with the previous post.
Snakes regain stomach acid much slower than we do. Because they don't chew food it's also much more powerful. If the snake eats right after a regurg it has no acid to break down the prey item. It will most likely shoot this back out as well. Regurg is recurring if done often, similar to belhemia(sp?) in humans. If someone uses their finger to induce regurgitation eventually the stomach will no longer hold food down, same deal here. A minimum of two weeks should be allowed before offering again. Snakes go months in nature without food, so 2 or 3 weeks is not bad for it. Offering a hopper instead of a small mouse is a good idea (apply this to what ever size you use, just step down one notch) and do that for two or three weeks then begin normal feeding. I would also go every 10 days for a little bit, but that may be excessive.
