7 weeks already eating a lot

I was never one who woke up hungry. Now I wake up starving. 
I was already eating in one of my favorite Spanish restaurants at 11:30am. I had two soups (yes hubbys too) chicken rice beans yuka.  I am only 7 weeks. Is it in ny head? Or do some experience the same thing. 
I was so full when I left... I think I'm getting hungry again. Wtf can that even be possible. Please share your stories.
