How many antacid tablets would one have to consume to lose stomach acidity?

If antacid tablets (like tums, for example) are used to treat exceptionally low stomach pH, then I figured they must be able to raise the pH of a healthy person's stomach as well. This got me wondering how many antacid tablets it would take to raise stomach pH so much that food becomes undigestable, at what pH that would actually happen, and what other effects this whole process would have on the person trying to consume so many tablets.

Tl;DR: how many antacids does it take to make you sick, and how sick would you get?

Stomach pH doesn't have a whole lot to do with digestion. There will be some enzymes that do not work as well in the stomach but digestion happens primarily in the small intestine which is a more neutral pH. The acidity of the stomach is primarily a defensive mechanism to destroy bacteria that are ingested.
