As far as cures go, I have found some home remedies in case you are experiencing lycanthropy (or more commonly known as Wolf-Flu). One states that while in werewolf form, three drops of blood must be extracted from the victim (seems to be a partial remedy, surely there is something else to that). Another home remedy is to avoid human flesh for 9 years (not really practical - especially if you happen to have some Buffalo sauce...mmmmm...). We once tried to cure a friend of ours by throwing him in the washer machine. Sadly it didn't work, but he did become a wash-and-wearwolf.
Other cures I came across:
* Convert to Christianity (Although, what if you are already a Christian? Are you immune?)
* Exhaust yourself - this is what the ancient Greeks believed would do it
* Exorcism - by the way, what do you get when you don't pay your exorcist bill? Repossessed!
