Firstly, it would be good if you implemented my General Eating Mechanics - rules for good digestion, which are listed here below.
•Always sit down to meals, pausing before starting to eat, just to catch your breath and focus on your meal.
•Eat slowly, chewing each mouthful at least 20 times.
•Don’t drink with meals, as this weakens your digestive enzymes.
•Sit up straight to give your stomach (which is located under your ribcage and is compressed by poor posture) room to expand and your stomach walls room to move.
•Don’t eat large portions, as this can put pressure on the stomach contents to reflux.
Tea and coffee can be culprits especially if you drink them with or immediately after meals. Mixing fresh fruit with other foods can be a problem for some people, and some find that spicy foods are particularly troublesome. Heavy proteins such as red meat are tricky for people who don’t have strong stomach acid or who are eating when stressed or hurried.
These rules usually improve digestive overall quite a bit.
Next, try taking 1 tbsp Silicol gel in a glass of water half an hour before meals (all of them if possible, but definitely main meals). This is only if you are not on any medication, because Silicol can't be taken within 1 hour of medication from the doctor. It is very soothing and calming, and should reduce the burning sensation and the need to rush to the loo.
