My husband buys Nestle 70% dark choc. bars when he goes to Europe. They do not have these bars in the US. You can't even order them over the Internet. He usually buys 12-15 at a time. Since he doesn't usually travel in the winter we are down to 3. We each eat one piece (2 squares) after dinner, which pretty much eliminates any cravings for me. If I am going out to dinner, I eat one after lunch.
If we run out of these, we buy Lindt bars, not sure which one. And our chocolate is not hidden. As long as I eat my one piece a day, I'm fine. I never eat candy otherwise. I do have a chocolate dessert once in awhile, mostly on special occasions, or if we are at a really nice restaurant. Most of the time, I'd rather pig out on a pizza!
