Sexy Vampire Books

It's no secret that I love to read and that I'm a big fan of the Twilight books.  I've read that series twice and I'm always getting suggestions from friends about similar books.  Some I have enjoyed and some I thought were just so-so.  There is one series however, that I can't seem to put down.  It's called The Black Dagger Brotherhood series... and the stories are literally keeping up at night. (DISCLAIMER:  The Black Dagger Brotherhood Series is ADULT fiction.  Lots of sexual content.)  I've been trying to pace myself.  There are only 6 books in the series and I'm on number 5 but I can't put them down.  I've forced myself to put a week or two in between each book but once I start the story, I can't stop.  My obsession is so bad that I don't get anything else accomplished.  I should be catching up on housework, errands and paperwork on the weekend, but instead I wasted THE WHOLE DAY reading.  I did manage to get the laundry done, but I literally had to set a timer to remind me to switch the clothes from the washer to the dryer.  I can't believe how fast an hour goes by when you're buried in a good book.  I'm going to use these as a reward to getting things done.  I've been a terrible procrastinator lately so this is going to be my cure.  I can't read another page until I tackle at least 2-3 projects each night.
