My only experience with this is for chronic metabolic acidosis due to renal failure (in a parent) - there are sodium bicarbonate tablets in 325 and 650mg. Taken multiple times a day. Somewhere around 1500-3000mg/day. Looks like this study was working with a single amount of 2g dissolved in 250mL.

I had suffered from dueodenul ulcers, and was hospitalized, almost died.

This was right before my 21st birthday, so afterwards, during that time in my life, I attended alot of parties, but my stomach would often sour (time of night, food, etc.).

I was not much of a drinker, but I would use baking soda at house parties when my stomach started to turn.

I would not do it daily, but 1 tsp dissolved in approx 6 oz of water as needed.

Works within 15 minutes.

It's basically what alka-seltzer, long-time hangover cure, is made of, with a little aspirin added.
