Fallon in Morthal.

Also, sneaking up on people to feed is easy. At stage 4 you should have invisibility, calm, powers that mean you should never get caught, plus you get like +20% sneak with Vampirism.

how do you know what stage your at?i was just standing over someone sleeping at 3.30 am and the only option was to talk to or in sneak to pickpocket them,i have 25% better sneak in my active effects and the resist poisin and fortify illusion and invis

You can tell by your resistance stats. Just try and feed at every opportunity, because it's not that hard.

Oh, and it's Falion in Morthal. Darn iPod auto correct.

As I mentioned your other thread you may not be a vampire yet and just have the disease that causes vampirism.
Try drinking a cure disase potion

In stage 4 everyone attacks you on sight. Thats how you know So if you can 'talk' you're not in stage 4 and can go to fix vampirism.

Some NPCs are immune. Can't feed on everyone.
