my mother is so dry from inside gut that she trys to take vitamin B5 it would like someone sucks the moister out of her stomach and it gets very hard and tight, so tight that she can't even urinate. dos samething with vitamin A and Calcium bloats her stomach bad. She had digestive problems before the chickenpoxs. PPI and H2 blockers do the same. her stomach is so acidic and dry and thick foam. her mucosa. seems to be gone. also she drinks 10 bottles water everyday and still dry inside and out. again shes been to doctors no help.
