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.

sneak, select the pickpocket option > then click feed.

I have tried to sneak, but when i press E to pickpocket i don't get the option to feed, i just enter the inventory of the sleeping person. :/
