The symptoms could be due to
acid reflux or GERD, or due to
hiatal hernia. Omeprazole is a good drug to
combat this. Along with it you can try over the counter antacids. Avoid heavy meals. Avoid too much of caffeine, tea, fried food and drinks both alcoholic and non alcoholic fuzzy ones. Avoid heavy exercises within 4 hours of a heavy meal. Raise the head end of the bed by pillows to 30 degrees. Go to bed at least 2 hours after food.
