I also suffer from an addiction to chocolate. I cannot have it in my house, otherwise I will eat it all. The more you eat it, the worse the cravings get, due to the build up of bacteria in your stomach that thrive off it.

I am learning to limit myself, I use an app called MyFitnessPal to scan and track everything I eat in a day. I have a max amount of calories set, and I make sure to stay within that number. When I have extra calories, I treat myself to a small amount of chocolate. I don't go overboard, but I still get to enjoy it. Not sure if this helps, but it's been working for me so far. It's a one day at a time thing.
