Dracula is addicted.

"I'm told they found me passed out on the sidewalk outside the 9th Street blood bank. It was nearly dawn, and apparently I was incoherent and didn't know where I was. All I know is that the urge took me over completely. I had to have my medicine. That's the funny thing about my condition--no matter how bad things get, no matter how much I lose or how many people die needlessly, that red stuff makes everything better. Tolerable. It's the only way I can bear the incredible burden that is eternal life. I need blood to live, but I feel like it's killing me."
