I would suggest 3 things to solve your digestive problems:

1. Give up or at least cut down on most dairy milk products (especially milk), and switch instead to an Almond milk, such as Silk, Blue Diamond, etc.

2. Do not take any kind of ant-acid pills, such as pantoprozol, or even over-the-counter ant-acid products. These pills do more harm than good, primarily because they remove acid from the stomach, which is actually quite the opposite of what is really needed. Without sufficient acid in the stomach to digest food, all kinds of problems can and do develop.

3. Get and take a good digestive enzyme with each meal. These will help digest your food properly, and will also assist in restoring balance to your whole digestive system.

Do all 3 of the above, and I think your digestive problems will be relieved in almost no time, and with zero side-effects. If they are not relieved, then I would suggest getting tested for H. pylori. If the test comes back positive, you will need to be treated with at least two different antibiotics daily for 10-15 days so as to get rid of it. And then you will be fine.
