Instead of drinking the horrible tasting water with baking soda, you could swallow a couple of small Sodamint tablets before bedtime. They are usually sold in pharmacies in Thailand at 150 Baht for 1,000 tablets. However be careful with baking soda (and Sodamint) if you already have a high sodium intake. I have succesfully reduced my daily salt intake, which also resulted in way fewer GERD and Heartburn situations. But a person would still have to find and avoid the foods and drinks that triggers GERD and Heartburn.
