Sugar is one of the main culprits that causes my acid reflux, so I wouldn’t use anything with sugar in it or on it. I have reactive hypoglycemia as well. If I eat sugar, I just bounce off of the walls for awhile then crash and burn and all I want to do then is sleep. I don’t even use sugar substitutes as I worry about them causing cancer, anything sweet just tastes nasty once you get used to not having it. I drink unsweetened tea instead of sodas and just don’t eat sweets. Even some fruits such as strawberries will affect me badly. I don’t use salt either, it makes me bloat horribly.
That must be so difficult. Have you tried low sodium club soda? That seems to be helpful as well.
