well, I would be surprised if he didn't do this. Seems they all do when fed that much. Do not worry. Just let him be. Wait a few days, offer a cricket or two. If he doesnt' eat it, take it out. Repeat. The key is to keep them hungry. They need a fraction of their appetite to stay healthy. Without parasites and the stresses of the wild, they dont' need to eat that much to maintain their weight (or even grow normally).
The difference between what the CAN eat,a nd what they NEED to eat is amazing. My first male veiled could eat 20+ adult crickets a day. For about 2 weeks. Then , he'd not eat a thing for weeks.
relax, let him go hungry for a while. He'll eat. But keep him wanting more - ever stuff him. You will not likely see this problem again.
