I have a lot of gastric problems. Gas usually sucks on my chest foe almost 2-3 days. Very strong tablets even don't work. Whenever it happens I get burp for almost 3 days. Get almost 8 burps in a minute. Pls help. Also please suggest me some ayurvedic supplement to consume daily with no side effects to improve my digestion and to avoid gas problems. Note- I drink almost 1800 ml of water per day. I eat very less amount of. Fast food. I don't drink, smoke,or take tobacco or gutka. I go to gym also. Boil vegetables or meat before cooking.
