too much cake

yesterday was my friend marie's birthday so i baked this big huge 5 layer chocolate cake and everyone said it was too sweet but oh well they couldnt resist eating the whole thing even if it gave them cavities hahaha. anyways now every time i see a bakery or something idk why but i feel like im craving more sugar. my husband says its normal for someone my age, am i crazy though? i do feel kinda jittery sometimes from all the cake and candy lately. what do you think is going on here?
