Baking soda will not do harm as fast as OTC or prescription meds, and may be used in an emergency.
Something called "tri-salts" that is a mix of potassium soda, baking soda and citric acid is a far better choice. Home made, it is quite inexpensive. This is the same as "Alka Seltzer Gold" but many times cheaper!!!
Either of these may throw off one's balance of minerals and "live carbon" very badly if used to excess. This means if you try to use it every day, nearly every day, or more than once a day, you have a potential medical emergency on your hands. This is not necessarily a crisis but slowly subtly accumulating chronic degeneration in one's health. This was happening to me b4 finding the Moreless protocol.
Use of these things once or twice a month if no alk drink or honey and ACV available might be tolerable. But even this should direct one to examine their food choices and lifestyle. The goal should be NEVER to either need or to use these!!!
Also, the appropriate detox bath taken in eve b4 bed generally alkalises whole body and may assist with reflux as well as overall pH! Relaxes one and aids sleep, also.
