Don’t just focus on fields, sometimes changes in food can be much more effective and quick in solving problems than fields, I also had reflux, but after using apple vinegar diluted in water I never had it again, water with lemon and ginger are also very effective in resolving this.
In addition to audios avoid all foods that contain insoluble fiber. It is irritating to the intestines.
Also if possible avoided some difficult to digest food mix.
Ideally it would be better to do intermittent fasting, consume vegetable broths and easily digestible foods
Be careful though not to go against your will not to want to eat at times . This is a normal and instinctive reaction of the body when you are sick. As for a child or an animal which is sick it does not eat during a moment . The internal healing of the body takes place more quickly when it is not in a process of digestion.
