Thank you Laja. I think a lot of the Medical Industry runs on a well practiced inertia to protect their business model. I am going to cancel a scheduled Oct.16 endoscopy/colonoscopy that is supposed to determine what is "wrong" with me. I have absolutely no doubt what is "wrong" with me, and I do believe "fixing" myself. I went on two separate rounds of heavy tetracycline during my Covid infection era, for 2 episodes of infected cysts. I can't rule out a role possibly involving those antibiotics in triggering an auto response to so many previously easily digestible foods. I was like you, thinking of water as an allergic response. I switched to bottled spring water for my hydration and I must say it hydrates much better. At my worst, a few months ago, at the height of the constipation, I was walking 3 miles/day, drinking 2 cups of prune juice, and ingesting 5 litres of tap water DAILY!! I was literally killing myself, depleting electrolytes to stay alive and go to the bathroom on an at best somewhat regular basis Thanks again for much appreciated reponse to "My story". I sincerely hope that this will help more people get this figured out on an individual dietary basis. It will not be a "cookie cutter" Big Med solution. Personal diets for every individual covid GI long hauler is probably going to be the difference maker. I also sincerely believe, at minimum your drinking water for hydration must be at least filtered public tap, but ideally bottled spring water of some type.
