I started eating primal this week and have been doing good until yesterday. After eating I had this rock hard feeling in my upper stomach, almost feels like food or gas stuck in there. It doesn't really hurt but its uncomfortable! Then today again after eating I have the same feeling. I had a few squares of dark choclolate today and yesterday, but I never had stomach problems before going Primal. I am eating meat and veggies a little coconut milk, cream and cheese, and have had fruit a couple times.
