sore throat/ Stomach Acid and old folks

And, while you're on the subject, the ENT said the sore throat I've had for a year is from acid coming up and I need to take antacids.

I don't want to because of all I learned from you about older folks having low stomach acid- and my digestion is lousy. I guess the thing to do is eat smaller meals and not lay down after eating. I also have Bragg's ACV and water in a thermos next to my bed and drink some at night and in the morning. I don't have heart burn anymore.

What about taking very small pieces of tums (calcium carbonate) throughout the day?

Any more ideas how to keep the acid from coming up?
