What you are describing sounds like pretty bad acid reflux or GERD. Get some Bromelain which is good for your digestive system. Also, get natural apple cider vinegar and natural honey. You can either put one tablespoon of each in one liter of distilled water and drink it. Three times a day if you can. However, I absolutely hate it that way. The way that I do it and that it can also be done is one tablespoon apple cider vinegar, one tablespoon of honey. Put in a cup. Stir very well. Have ice cold distilled water or pomegranet juice, or unsweetened tea, something healthy within reach. Drink the apple cider vinegar cocktail followed by the ice cold drink chaser. Do this three times a day with every meal. It will get rid of your acid reflux.
It may taste bad but it is worth it. Apple cider vinegar has a plethera of health benefits. It even relieves anxiety and depression.
