Just get Dawnguard. It is a great DLC with nice weapons, nice locations, nice dragons, nice people and a very nice vampire lady. The only issue with it is that one quest is overly long, but it is worth every single cent, trust me.

After you join the companions, getting werewolf will remove vampirism. You can get it back later.

Dawnguard also adds a useful potion for vampires in your position, but again, Dawnguard makes the potion useless.
