First, let me say, I don't have a corn snake. But we are planning on getting one for my daughter, so I've been reading up about them.

When I saw this thread, I immediately remembered a similar one from only a few weeks ago. The advice there might help you.

Also, in that thread, Connie (littleindiangirl) posted this link to an article by Kathy Love about what to do when a snake regurges. I'd assume since it is Kathy Love and it is on the corn snake forums, the advice is specific to corn snakes.

You said you tried what Kathy Love said, half a pinkie. I don't know if you meant this article or not. If so, it sounds like you may have missed what I interpreted as what Kathy Love was stressing more... wait, don't rush, leave the snake alone...
