Excessive crying
Searching on the internet for vampire news
Intense longing for the next movie/series of your favourite vampire story
Re-reading vampire books
Compulsion to buy the overpriced fangs you saw in the shop even though it's not halloween
If you have one or many of these signs then OH NO! I'm afraid you have Vampire withdrawl! But don't worry, these symptoms can be cured with a few easy methods I've come across in my time:
Go to Damon/Edward/whoever you like land...
Eat a bucket load of ice cream/ nutella while watching 17 hours of the previous series/ movies of a vampire show (IN BED!)
Count down to the next episode/ movie of your favourite vampire show.
However, these remidies may not fully cure your lust for vampires :( we will all just have to wait to see the next instalment into the series :'(
