Please try a quarter to one half teaspoon of black pepper. Chew pepper without any liquid until it is a pastei your mouth. Then swollow it. You can ad a pinch of salt to the pepper beforehand to help make saliva. Take a little water, not too much.
This has helped me with acid reflux (CURED IT), Stomach cramps, flu cramps, or after eating bad food. In a few days it may go away. Watch what you eat and what makes it worse. Do not eat before bed time, important!
Hope it helps you. Don't do the purple pill, its bad for you. Pepper and easy to digest foods will help.
