Hello I share your concern You are taking right medicines, you need not to worry much In my opinion nexium is better than zantac Apart from medicines I would advise you following life style and dietary modifications Don t lie down immediately after food Have small and frequent meals Have lots of fresh fruits and vegetables Avoid fatty fried spicy and junk food or carbonated drinks Complete abstinence of alcohol and smoking Try to reduce body weight if you are overweight or obese. Hope this helps you Please feel free to ask for more clarification, I will be happy to help you wish you good health
