Yep, the burping I get. I have an idea. I heard of 1 person who got rid of his iwth gripe water. It turns out gripe water is antispasmodic and found another that got rid of his with a pharmaceutical antispasmodic. THat doesn't get to the root of course but does provide a clue that the problem might be caused by spasms. Then the question is what is causing the spasms. I know Tapeworms in teh ileocecal valve can cause that - maybe other parasties can too. I know you tried a pharm antiparasitical but maybe more is needed than a single treatment. What do you think ?
