Hi, I started out taking Caltrate + Vitamin D - it's one pill. That helped my stomach. I also take Acidopholus. These can be found in health stores, and pharmacies. They aren't very expensive. As for eating, I eat small meals, every few hours. It takes a lot of work for your stomach to digest big meals, so spread them out. I don't eat dairy or red meat - both of those your stomach has to create the enzymes to break down the substance, leading to more work for my already angry stomach. I also don't eat fried foods - especially in restaurants!!! I stay away from too much sugar, really spicy foods, and fatty foods. It may sound like everything, but it's really just eating foods moderately. For exercise, I recommend yoga, it really does help. Some exercises you lay down for, some you stand. You can choose, and at your own pace. It also helps you breathe, which relaxes you and helps your digestion. To start out you could just stretch, because it is using your muscles, and relaxes you. Also takes deep breathes while laying down. It relaxes your whole body, including your stomach. Good luck to you. You can get through this.
