What are the reasons I'm craving lemons and spicy foods lately?

Lately I’ve been craving a lot of spicy foods and lemons lately… When I eat spicy food or put spicy sauce on anything I put it on so much it makes my eyes tears and mouth burns. When I eat lemons I eat about 4 or 5 wholes of them at a time… I’ve been craving spicy food as well for the past 2 weeks. What in the world is the deal? I’m not pregnant so what can it mean? I’ve had urges or lemons before too in my past, like years ago randomly.
