found this article on reddit last year and have been trying this freqently. There are a lot of other exercises ( including some yoga ones) on youtube. Nothing seems to have made any difference for me so far, unfortunately . I also had upper endoscopy, barium swallow and other tests but none of those found anything at all. PPIs and such don't do anything. I've tried other 'home remdies' like apple cider vinegar, drink…
Did you try cutting out 'enriched' flour? That seems to be a major trigger of heartburn for me and I do a lot better without it.
intresting. we mainly eat rice but i do eat bread once a week. I will try to cut it out .
