When adrenaline rushes through your body, your blood goes to the places that your body feels need it most. That means that your blood is rushing to your heart, your brain, and possibly various muscles, and to do that it rushes out of your legs and makes them feel more like jelly.
Since acid is a primary cause of ulcers, you want to completely avoid any foods with high acidic content. Among them: alcohol, black and red peppers, chili powder and hot peppers, all of which irritate the stomach lining, and coffee, tea, colas, or chocolate, which can increase the amount of stomach acid.
Consuming foods that are more ulcer-friendly instead may reduce pain and help your ulcer heal. Beverages Caffeine-free beverages and low-acid juices including apple, grape and pear, are generally safe if you have a stomach ulcer. Drink mild herbal teas and plenty of water. Avoid all caffeinated beverages, including coffee, tea and cocoa, and do not drink alcohol. In addition, avoid all citrus and vegetable juices, which are high in acid.
