Having a pretty empty stomach and intestines can cause large gas bubbles to form. I often get pretty bad pain when I need to eat because of this. However, then I get pain from the actual food...sometimes you just can't win. But maybe try to eat a few little snacks in between meals if you can, even just a few crackers. That should help prevent gas pains. And also, when you do have really bad pain, try gently rubbing your tummy. It helps to break up the gas into smaller bubbles that you can pass
