Craving Garlic

I have been having an insane craving for garlic, I'll add it to EVERYTHING - like CLOVES of it... I know people say when you have a serious craving for a specific food you are normally lacking something - mineral, vit, etc. Anyone know what might bring on a garlic bing or what it might mean? I've always loved garlic but not two or three times a day on everything from eggs, chicken, shrimp, crab, toast, rice and EVERYTHING else i can put it on... Thanks for the ideas, Cass
