I just started a detox diet today... that basically goes with what you're trying to do. I'm buying organic and gluten free (for celiacs) and trying to eat mostly raw fruits and vegetables. Today wasn't a great day as I became very sick. I would recommend making changes slowly to your diet taking weeks to complete the transformation especially when you have stomach problems. Although because you're already a vegetarian this should help. I am currently using herbal tea and drinking lots of water with lemon squeezed in it as well as taking more vitamins. Good luck with your new pursuit and that's awesome that you found an organic farm so close!
