Yes u can control acidity n heartburn etc. with these lifestyle changes. Do this 1. Don't take tea empty stomach. Eat something like a banana (if you are not diabetic). ) or any seasonal fruit or soaked almonds and a glass of water first thing in the morning (within 10 mins of waking up). No only biscuits or rusk will not do. 2. Don't Overeat 3. Take your breakfast every day. Don't skip it. U can eat whatever ur mother or grandparent eat in bfast. I mean to say whatever is ur traditional food. If punjabi eat paratha, if belongs to south then take idli/ dosa etc. 4. Have light meals every 2 hours (in addition to your breakfast, lunch n dinner) e.g. Nariyal paani, chaach, a handful of dry fruits, a handful of peanuts, any fresh n seasonal fruit, a cup of curd/milk etc 5. Finish your dinner at least 2 hours before going to sleep. 6. Maintain active life style 7. Avoid fast foods, spicy n fried foods, Carbonated beverages 8. Take a lot of green vegetables n fruit.

This is for long term results But for now to bring your digestive system back on track you need to take medicines. For that I need more details, you can consult me
