Hi! Congratulations on your pregnancy!
I'm afraid I don't have a lot of advice about cravings. I had a few cravings during my first trimester, but nothing too bad. One time I wanted french fries pretty badly and I gave in then. A few other times I wanted ice cream, which I did, but I stuck to the low-fat versions. I mostly craved watermelon and strawberries which I didn't mind eating. I've read that if you have cravings for unhealthy food, it's okay to give in occasionally so you don't go crazy depriving yourself, but if you can find healthy substitutes, that would be better.
Sorry - that's probably not very helpful. I would say not to let yourself feel guilty if you give in to unhealthy cravings now and then.
