I also was taking TUMS when I was more acidic, but instead it made me nauseous
and gave me stomach pains. In searching, I found that the
symptoms of high acidity and low acidity are the same. Depends on your age .. As people age, everything gets lowered. The advise I got was to take Magnesium Chloride two tabs with each meal. My acidity was much better although I still have to manage gas with anti gas enzymes before or after meals. And yes, I did stop taking my prescription.
