Are you feeding live or ft?
The course for after a regurge is no feeding for 2 weeks. Then feed a very small prey item. Then wait another two weeks if he holds it down slightly bump prey size and try feeding on a regular schedule. If things keep going well you can go back to feeding normally. He needs time to get the bacterial load back to normal and to heal up from the regurge. Forcing food to soon is just going to make situations worse. But now you need to try and find out why the regurge happened. So ft or live, weight of the snake, and prey size?
