I hate to say it but any symptoms you have with your digestion, feeling sick, having heart burn, bloating, diarrhea, constipation, it is a food intolerance. The thing you have to do is figure out which food it is that is causing it. The biggest culprits are GRAINS and DAIRY - Cut out gluten/wheat, see how you feel, next try dairy, you can also try cutting out rice and or oats. For me it was grains and Dairy. I now follow a paleo way of eating and feel amazing, my stomach is healing, I've lost weight (60 lbs), I have more energy, my skin is clearer. Do the research and do an elimination diet of some sort. You'll be happy you did! Take care!
