Detailed Answer:
Hi,
Thanks for choosing HealthcareMagic for your query.

As per your query,
Firstly I would suggest you to switch over to Nexium(Esomeprazole). Initially take it 40mg twice daily, However if not relieved doses can be increased to 80mg twice a day.Though Esomeprazole is of the same class as Pantoprazole yet trials show it is superior to other PPI's in treating reflux disorder and severe acute dyspepsia. Protonix 1 per day is a bit low dose as per the intensity of your symptoms.
On the day of appointment ask your gastroenterologist to add Prokinetic drug like
Option 1
Levosulpride-It is a sulpride isomer and exerts its prokinetic effect by blocking D2 receptors. Recent trials have shown that combining it with PPI's have excellent effect in patients suffering from acid reflux.

Option 2
Domperidome-Very effective in treating reflux not controlled by PPI's especially when combined with Rabiprazole.

Acotiamide- Trials showed that 30mg doses taken thrice daily were highly effective in treatment of of dyspepsia.The positive effect of acotiamide on both gastric emptying and gastric accommodation,Gastric accommodation and gastric emptying in acotiamide group were significantly enhanced in people taking it.
Just taking natural supplements will not do as you are having severe dyspepsia due to long term antibiotic therapy.
These medications suggested above should be discussed with your Gastroenterologist. Ask him /her to increase the doses from minimal to optimal.
Mucous is because of severe irritation of gastric and esophageal lining by acid reflux.It's a natural protective phenomenon.To prevent mucosa from damage body secretes large amount of mucous to trap irritant's and prevent their direct contact with mucosa.
As reflux will settle down,mucous production will automatically stop.
Strict adherence to the diet suggested below is required along with medications-
-Take a low fat easily digestible food.
-Eat lot of raw salads esp. vegetables.
-No alcohol or smoking.
-No aerated beverages or soda.
-Avoid meat or processed food.
-Avoid cheese, Dairy,Milk etc.
-Take a lot's of yoghurt in food.
-Avoid spicy or fast food(No pizza or Burger).
-If possible try vegans diet in dinner and normal diet in lunch.
-Drink at least 8 cups of water everyday.
-avoid all fruits which are citrus.Avoid orange or pineapple juice.
-Eat 1 cups of fruit like banana daily.

You can go for a Endoscopy if not relieved by above suggested treatments.

In case of further query feel free to ask.

Thanks.
