I have exactly the same as the original post. Sour bicarbonate water brash. It's like a mix of clear serum and white foam. It sometimes makes me feel nauseous. I have been diagnosed with hypersensitive esophagus as my demeester score was only 13 (8 alkaline) I have 20mg of Elavil per day which has reduced the sour fluid a little. I have to eat low fat, drink plenty of sips of water and chew gum to feel any relief.
I have been told by Dr Kouffman at the New York Voice Institute that fundo is the solution for people like me who have this problem but live in the UK.
I agree the water brash seems to aggravate my throat tissue and palate so the PH of 5 would not surprise me.
Please post if you have any other ideas of how to relieve the problems
ps mine is worse when I bend my head forward for some reason whilst I am sitting. Very strange and frustrating condition!
