I think it is important to give this a good chance. It can take some time for the symptoms to go away. I have only been symptom free for the last couple of months. And they come back as soon as I eat stuff I shouldn’t ,like dark chocolate . Otherwise I don’t actually count FP. I did for a few days, then realized, as long as I stick to the low FP foods, I am in the 30 range.
I still get some mucus in the throat, but don’t have the hoarse voice anymore. But as long as my esophagus isn’t inflamed I am happy. I don’t feel that this can be cured, only managed.
Good luck with your doctor’s appointment. Hopefully he/she has an open mind.
