Breast Feeding Moms- Food Cravings?

Options
My baby is 3.5 months now--- at first I craved nothing but sweets--still do, but found that it helps if I just don't keep them in the house ;-) anyways, I have been craving eggs daily-- I don't even like eggs normally but for the last 2 months, I crave them--- I end up eating them about 4 days a week---- anyone else having wierd food cravings now that you are nursing? What would cause that?
