For a vampire craving blood? That's not really a medical question I'm equipped to have an opinion on. Maybe? I'd been meaning to ask you: I can request that Eve supply blood bags to you. Dunno if that will work or they'll have it... but it might at least take the edge off. Beyond that it would be working on your self-control, making sure you're with someone who can physically control you if you go into a frenzy again.
