My variegata won't stop too, can hear them from the other room lol. When I had orientalis they did the same.

That sucks, must be gutting. I've heard other people having these problems too. When I first got mine they were very small, but not just straight out the water. They basked quite a lot then, but did not eat well at all unless kept warm. I might try raising mine warm (if I'm lucky enough to get them to toads) in tanks with lots of aquatic plants and cork bark raft, so I don't have to really mess about with them. Cheers
