So the midnight feedings have you down or for some other reason you just don't
feel like you want to be a vampire anymore, luckily there is a way to cure it
without having to resort to loading a saved game. Anyway regardless of why you
wish to no longer be a vampire here is a quick run through of the quest.
The first step is to talk to Raminus Polus at the Arcane University, he usually
hangs out in the lobby so you don't worry if you are not a student at the mage
guild. When you speak to him ask about "Cure for Vampirism", unfortunately he
doesn't know of a cure but sends you to Castle Skingrad to speak with Count
Janus Hassildor. You can't speak directly to the count so talk to Hal-Liurz
first. Eventually you will be able to speak to the count, and he'll tell you a
story about how him and his wife are vampires but his wife didn't accept it so
he is searching for a cure for her. He will ask you to help him, when you
agree he tells you about a witch that knows more about the cure. He marks the
location on your map.
Follow the big red arrow on your compass / map to find the hut that Melisande
the witch lives at. When you talk to her, at first she plays dumb but
eventually she spills the beans and agrees to help you if you help her out with
something first. She wants you to get her five grand soul gems, your best bet
would be to buy them from the mages guild around the world if you are a member.
Also sometimes you can get them as treasure from dungeons. When you return
with the gems she gives you the next portion of the quest. You have to go and
collect the following ingredients for a potion:
6 cloves of garlic
You can find the garlic in peoples' houses in Skingrad
5 nightshade leaves
Can find Nightshade growing Southeast of Skingrad
2 shoots of blood grass
Blood Grass can be found in Oblivion or outside any of the Oblivion Gates
Also you need the blood of an Argonian, which when you speak to Melisande about
it she gives you a special dagger for the job. It can be any Argonian and also
you don't have to kill them just hit them once with the special dagger and that
should be enough to complete this part.
Finally you need to kill a powerful vampire named Hindaril for his ashes. When
you ask Melisande about it she marks the location of where to find him on your
map.
I've heard that if you turn in the items in the wrong order that it bugs your
game and you will have to reload a previous save if you want to complete the
quest. The order I turned in the items was blood grass, nightshade, garlic,
Argonian blood, and finally vampire ashes.
She gives you two potions, one for you to drink and one to give to Count
Hassildor's wife. After some waiting around and cut scenes you receive a 1000
gp reward for your hard work.
