I had bloating and constant burping for some time. The burping felt as if it started from below my navel and was very deep and loud. I was burping with each exhale and could not even sleep at night. It was suggested that I was swallowing air which I knew was bunk, because it started suddenly. My doctor felt it was started by stress. I did not believe him so I go on internet. I found that bacteria in my gut could have started this problem. I began taking eight drops of the oil of mountain wild grown oregano is a spoonful of olive oil three times a day. Also purchased a colon cleansing product and began taking it. After three days, the burping subsided to around three burps per hour and shortly after disappeared. Oil of oregano is very good at killing unfriendly bacteria and candida. I am disturbed that my dumb doctor did not know of this. I has suffered a long time and lost a lot of weight until I figured this out. Also, I had quit socializing altogether. If you have this problem, try and see if it helps you.
