I just found a cure today in the Mikona marketplace. It was 4500 gold. I can't remember the name of the vendor but she was kind of in the north/south middle section. I hope that works for you.

While I don't know how to cure it, I have heard that belladonna can help you resist your initial infection so that you don't contract lycanthropy.
