There is a potion that cures just about everything. I think its called potion of cure
disease.

Once your a werewolf you can't get rid of it. You are a werewolf forever, start a new
game.

Do the quest blood's honor you must have a witchs head than fight your own wolf spirit did
it help?

Take all the witches heads and after curing kodlak throw a head for yourself in. Once you
are cured you cant go back for memory unlike been a vampire.

Blackdragon99 was right and to the guy whose title was "wow" you are wrong there has
always been a cure to lycanthropy and its unlike vampirism because its an automatic change
so you can't cure it with just a potion of cure disease
