Obtain an object that used to belong to your ex-lover (it could be an article of clothing, a letter, anything). You will also need a tapered candle and some scented oil or perfume. Take the candle and mark your name across the object. Douse the object in the perfume/scent of your choosing. Light the candle and chant:
Twitter and Facebook, increase my willpower, so that I may achieve my goal. Give me the power to resist anything that may block my path!
Blow out the candle and dispose of the object.
