I just want to follow Deborah and CALM and stress the importance of not feeding again for 2 weeks.

It takes some time for them to recuperate after a regurge and feeding too soon can make matters worse.

Also, for the next meal, offer a prey item that's a bit smaller than you typically feed.

Assuming all goes well from there, resume feeding on regular schedule and with appropriate sized prey items.

It's also important to try to figure out WHY this happened and correct it if possible. Double and triple check your temps, husbandry, etc...
Is your heating equipment functioning properly?
Is your thermostat functioning properly?
Are your thermometers functioning properly?
Is the enclosure clean and is clean water always available?
Lastly, are you buying your feeders from a reliable source?
