Haha, I see what you did :)
I guess it’s like an addiction. I crave cigarettes and savory junk food, myself… It’s just a matter of what you allow yourself to get used to. (For instance, lots of people have tried cigarettes, or smoke them socially, or only when they drink, etc., and never crave them. I’m NOT one of those people!)
Chocolate has theobromine in it as well as caffeine. Plus I think it makes you release endorphins. Just like sex ;)
I never craved chocolate until I started eating it. The more I eat chocolate, the more I crave chocolate. I never even really cared for chocolate for most of my life, but I do know that when I eat chocolate I want more chocolate. So, for the most part I just don’t eat it.
I personally crave chocolate because it makes me feel good. I can’t get enough chocolate. It tastes fabulous, it comes in lots of delicious varieties, and it just flat out makes me happy.
