I have gone to drinking mostly water. The first few weeks I had terrible heart burn from drinking so much water. I thought maybe the soda and tea does a better job at coating my stomach to help keep the acid reflex down. I learned thought if I buy and drink water with a hire PH level I don’t get heart burn like I normally would. So now I pick up water that has a PH level of 9.5 or higher. I have not had heart burn since then!
