There are various tools you can use to convert from pdf and epub to the mobi format that the Kindle app can read. The one I use is Calibre, and it works pretty well.

Irritation of the stomach from spicy foods, smoking, alcohol, or infection with a bacteria called Helicobacter pylori may all cause symptoms of indigestion, which might include excessive burping. Burping is rarely a sign of a serious medical problem.
When you have sulfur burps your body is creating a gas from proteins that contain sulfur. It is known as hydrogen sulfide gas. There are microbes in your digestive system that break down the sulfur and release it. Most often, these microbes are part of the âgood bacteriaâ and nothing to worry about.
