Not sure if any of you realize it, but Vampirism is one of the best things that can happen to your character in the game. You just have to be skilled enough to pick locks on houses in order to feed to keep your quests going. But when you don't have any quests, Vampirism is amazing. Dungeon diving becomes much easier, and you don't have to worry about getting any further diseases.
But if you really think vampirism sucks, you could have solved your problem if you had just paid attention to your active effects after you get done cleaning out a Vampire lair.
