leaky gut allergies bloating

had bad bloating and was treated for candida overgrowth with Nystatin. had bad hives reaction (allergy or yeast die off?) and since am allergic to practically everything I eat, even though I am on a rotational diet and anti-yeast diet. still taking antifungals, but I can only eat a dozen or so foods, and getting worse--bloating still there. has anyone on the forum actually been "cured" from leaky gut, and how? it is much worse than the candida problem
