Also being a pet store snake in the condition you describe I would wait for the first defecation and take the snake to the vet to be sure there are no internal parasites and no dehydration (though you can spot severe dehydration yourself - see medical section). Wait until the snake deficates and retrieve the defecation and put it in a baggie and take the snake (in a pillow case or box or what have you) and the feces in to the vet. To find a herp vet near you check www.arav.org - fecal exams are pretty much the best way to tell what is wrong with a snake... the fresher the better. If you must wait a day DO NOT FREEze the sample.
