Hi Trish - According to "Optimal Wellness", extended use of Antibiotics can trigger a yeast-related polysystemic condition (candida) that has potentially devastating consequences. The book has a chapter on yeast overgrowth, and you might want to read it. Based on the information in your first post, I'm thinking that that's the thing you should focus on first. You might want to re-post you first message (or a version thereof) in the Candida Forum . I've never had this condition, so I can't advise you how to heal from it.
