I've not been a Vampire long but I want to feed so I don't get attacked while I'm the cites. But no one sleeps in my game. Everyone is away 24/7, so is there anyway to feed?

No one sleeps? Weird. I know some merchants are always awake, but I thought the civilians sleep.
To answer your question, not really. I wish there was a way... a spell, maybe, a part of vampirism that would conveniently make a person fall asleep.

Would a paralysing spell work?

People do sleep, but you may find some in the house may stay awake. The real problem is kids don't usually sleep and will often see you. Best to have a good sneak skill to avoid a lot of these problems. Spells won't work as this alerts them to your presence, best to sneak up and feed.

That sounds like a good idea, haven't tried it yet.

Also is there a PS3 glitch that makes your Vampire appearance not work? I have the last stage of Vampirism but I look normal.

I've had people act weirdly with their schedules and be up and out when they should be sleeping. If their out of their house, I still get to raid it and if their sleeping inside I get to pickpocket them. But in your case I don't know what to do. I wish there was a sleep spell.

My hint(no spoilers)

Same with Guard Barracks

The jarls and stewards always sleep, feed upon them.
