Just a small mod I made for my vampire character who has a taste for more magical blood and was upset that eating a fresh, still-beating dremora heart she just ripped out did nothing to satisfy her thirst. 

Allows the creation of blood potions from Daedra Hearts that have the same effect as feeding for vampires. 

Once you start the game, a spell named 'Distill Blood' will be automatically added to your spellbook. Casting this will use up one Daedra Heart from your inventory and give you a potion of blood that will reset your vampirism. 

I've tested this on a heavily modded game and it worked fine, so there shouldn't be any incompatibilities.
