You should keep an eye on this. I just got done reading the book on reptile parasites by Dr Klingenberg. It is at work now but I believe a mucus discharge could be an indication of endoparasites. Check out the stool and make sure they are absolutely normal. Speaking of drinking too much, when I picked up a yearling Eastern yesterday (captive) it did in fact spit up some WATER. There may be some credence behind the previous poster's claim.
