Recently started craving meat

Hey guys, I've been vegetarian for a year and a few months and I've just recently started craving meat. I had no problem giving up meat in the first place when I transitioned, and the smell/look of it started to fully disgust me after a few months of vegetarianism. But lately I've been craving it. I'm just wondering what this is, why it's happening, and how to get rid of that craving without giving into it. Thanks in advance!
