Yes, I do have Dawnguard, but it's not what you're thinking of. Once you get Vampirism from Harkon, you can go cure it by either Falion or Aela giving you lycanthropy again. HOWEVER, she can only give you lycanthropy again once. You can also gain Vampirism back from Harkon once, and Serana I believe twice. After you expire those, you cannot gain them back. You can't be a Vampire Lord and werewolf at the same time without doing a glitch.
