Welcome to Healthcare Magic, 
Persistent 
hyperacidity can lead to 
gastro esophageal reflux disease and even in late stage to 
peptic ulcer. You have to take prompt measures to prevent complications and treat your condition. You may start with lifestyle changes and general considerations: avoid non- steroidal anti-inflammatory drugs like Ibuprofen or Aspirin, smoking, alcohol, large fatty meals, spicy food, coffee, soda, stress. From medicines: first line antacids( neutralize your stomach acid) such as  Maalox, Rennie, Mylanta, Rolaids, Riopan, 
Alka-Seltzer, etc.. Second line : H2 blockers such as cimetidine (Tagamet HB ), Ranitidine ( Zantac 75 ), Famotidine( Pepcid AC), Nizatidine (Axid AR).Third line : proton pump inhibitors such as omeprazole ( Prilosec,  Zegerid ), 
Lansoprazole ( Prevacid ), 
Pantoprazole ( Protonix) 
Esomeprazole ( Nexium) .
Practically you will start with any of antacids only   for few days  and monitor your self, if there no improvements add second line H2 blockers and monitor for few days. I believe first two drug groups will help you and no need add a third line (only in severe cases).  Follow strictly advice, diet and medication and you will have positive result. 
I wish you  good luck and speedy recovery, 
Hope this helps and I have answered your query. If  you have additional queries don’t hesitate to ask. 
Best Regards, 
Dr.Mihail
