Doubtful that it has anything to do with hrt, my endo told me that there is no proof that hormone changes have anything to do with cravings for anything especially for sweets. I always believed that menstruation caused women to crave certain foods especially sweets like chocolate but now i think it could just be psychological. My cousin goes crazy for sweets when she's on her per. and now i believe that its a force of habit. But hey its just my opinion and what ive been told. IT could be hrt but who knows
