Well, if you don't want to be a vampire, you should seek a cure. There probably is one; there was in Morrowind. If you do want to be a vampire, you should stop feeding; everything gets more vampirish when you don't feed...
I don't want to be one, so I'm finding the cure. The reason I'm feeding after every Wait or Rest is so that I can go out in the Sun. I like my sunlight I do.
