Hi Spence, Thanks for the comment. From my post, what makes you determine it is not blasto or d.fragilis that is causing my symptoms? I am still suffering from bloating and metallic taste/dry mouth, but I am trying to be patient as it has been less than a month and I am currently taking VSL#3 probiotics which are known to cause abdominal bloating. If I am not cured, any suggestions on which tests to request from a dr? Which parasite did you have? Thanks
