But baking soda is basic while HCl would be acidic?
i should note that the HCl tablets thing is something i picked up on in my 20s, apparently everyone had reflux back then, and most people just ate a tums or whatever, but a couple of folks had their doctors tell them it was because of weak stomach acid, so food was taking too long to digest, then you're laying down or whatever.
My little anecdotes are flavor, they're not relevant to HCl tablet efficacy (for example.) It's just an OTC thing that either works or doesn't. Ask your doctor today.
