I suggest you to have bland diet since you are suffering from acidity and
flatulence ,means as you already told its better to avoid oily,spicy food,have fresh fruit juices regularly,specially vit c containing like lemon,orange and musumbi juices,. with that do a course of HIMCOCID SYRUP 2tsp 3times a day half hour before meal,and UDHARASUDHA 15ml at night after meal.Dont skip any meal at any cost.
