Cravings during early pregnancy

I crave for both savory and sweet stuff but more for the latter. I did try to take fruits as alternative but it doesn't satisfy my craving. What works for me is to just allow myself to have only one or two small servings of sweet stuff a day. E.g. One square of chocolate / one slice of whole grain cracker with whatever spread I have/ if I have a glass of sweet drink that day I'll try to skip the sweet food. If I don't have sweet stuff for a long time I tend to binge, so rationing works for me. And I don't stock too much junk food at home. Out of sight out of mouth haha. Plus, I tell myself those things are just empty calories. They are adding pounds to me and probably not to the baby, since most of them are not nutritious.
