2/2
Yeah, food's pretty important, still, and all. It would be really boring if it wasn't. [...Although technically she could probably live without it, but that would take a large amount of the redder variety, she assumes.
She's never tried... doesn't really want to, either.]
Where I come from, blood isn't consumed for sustenance. Well - not like normal food, anyway. No one would die from not drinking it.
[Although that's not particularly fair, either]
But it... it is instinct to drink it. If a vampire was to go a long time without a drinking, or taking a supplement to curve those desires, their sanity and urges would begin to suffer. That individual would probably begin to lose some control over their senses.
