Vampires: why does your character drink blood? Options

[Lady Saga]

I am having trouble with this one, and need some ideas. Why does your character drink blood? Why do they feed?

In Oblivion, becoming a Stage 4 vampire caused the majority of NPCs to be repulsed by our characters. They technically did not have to feed, but at least once the feeding was done, the NPCs stopped recognizing that our chars were vampires. This essentially gave our characters a reason to feed, at least.

But in Skyrim, this is no longer so (assuming Dawngurd is installed). The NPCs treat our characters with mild suspicion at best, but going from Stage 1 to Stage 4 does not actually cause any wanton sorts of behavior from the world.

So why does your character need to feed? What RP ideas have you all come up with?

Welcome to the forums, BretonBlood. I see SubRosa has already christened you BB in one of our other threads.

I do like that Oblivion has the Count of Skingrad who has somehow managed to 'tame' (or at least deal with) the beast inside and actually seems to have no evil intent. Similarly, I'm pleased that the court wizard for Solitude (in Skyrim) seems to fit into the same category. Given their food source, and the resultant tension between vamps and peeps, it seems at least a couple have forged a different path.
