I guess the difference is that being an antivaxer can potentially harm society whereas trying a high fibre, probiotic rich diet can’t hurt anyone. And I completely understand the skepticism, which is why I couched my comment with “it may not work for everyone”.

> Did she at least tell the doctor "hey no worries my kid fixed it"? What did they say?

The answer is no: I told her not to tell her doctor under any circumstances that she got armchair advice from her “kid” that actually worked because if I was a doctor who went through 10 years of med school + training, I would definitely be rolling my eyes if some senior came in and told me this story.

The point is, I haven’t dropped any probiotic brand names, I’m not hawking anything, I don’t gain anything by posting my little anecdotal experience. I’m just happy that I found a solution to a problem that has been torturing someone I care about for 10-15 years and wanted to share it so that it might help others in the same situation.

Edit: to be clear, there were other things too that helped clear up her symptoms that I omitted because my post was getting too long and because out of everything, probiotics seemed to be the biggest gamechanger. For example: first few months she also took DGL (Deglycyrrhizinated Licorice, to promote mucus secretion) 15 minutes before every meal, followed by a digestive enzyme taken with the meal (she doesn’t actually need these anymore and only takes it as a precaution if the meal is particularly starchy or high protein). Cutting out LES relaxers like caffeine, mint and chocolate helped. Also lifestyle changes were made in terms of physical activity. She still needs to sleep at an incline on a wedge block, but at least she’s not vomiting all over the carpet anymore.
