How do I get over my addiction to chocolate?

Yes, I'm being serious. I crave chocolate all day every day. Since I was a little girl, I have had sweet things for breakfast (pop tarts, Little Debbie snacks, etc). I really do not care for breakfast food at all. I normally eat a chocolate chip granola bar and chocolate milk for breakfast. I'm having a hard time giving up my sweets (I've only been eating them for 25+ years)!!!!!!!!!!!!! How do I do it?
