Looking for a Season 8/9 body horror fic that involved Sam and Flies - FOUND

[annie46.livejournal.com]

I'm looking for a really creepy little fic that told the story of Sam after he'd stopped the trials (I think). He's with Dean and he feels weird - keeps hearing flies buzzing around him - finds stains on the bedding. It turns out that Dean bought Sam's corpse back to life and Sam is sort of living dead (I hope this makes some sense). I've searched and searched to no avail so any help would be awesome!
