If you are sure you are having gas, and not a problem with your pancreas (located on the left side behind your stomach
organ), may I suggest simethicone (gas
-x)? They have it over the counter and it is supposed to help with breaking up those air bubbles I believe. I had it prescribed for me when I was getting gas stuck in a sharp curve of intestine on the right- once after each meal and I think maybe at bedtime too many years ago. I use simethicone for gas as needed now.
