hello, i recently turn into a stage 4 vampire in skyrim and i want to revert this, mainly because i can't progress in the game and everybody is hostile.
My problem is that the only way to turn to stage 3,2,1 vampirism is to feed on the blod of someone who is asleep (Wich i'm aware off)
and the thing is that when i sneak up to someone to feed on them i don't get the option to do so, is this a bug or am i doing something wrong?
also i would like to know if anybody have a command to use to feed, or to remove vampirism. Thx alot for help.

Same problem here. Cannot feed, no matter what I try (no werewolf history).

For now, I created a hotfix: http://skyrimnexus.com/downloads/file.php?id=6417

Did you by chance use the 'showracemenu' command?

No after becoming a vampire.
