You don't want to. Its nothing like fictional works make it out to be! Its not fun, you are still physically "mortal" and alive, it does not improve your looks or chances with potential mates, no special fangs, not possible to change people - including you, it does not give you powers of super-strength.
Even if you could be changed or turned (which is subject to debate) it's not something that anyone would want!
Listen to me there is always a limit as to what a human being can do, And no matter how hard you try you will always be just another wanna-be vampire.... And remember this it is very possible for you to get very sick drinking human blood and yes you can even die..... So if you are as smart as I think that you are then you should stop yourself when it come to drinking animal or human blood period................
