that is exactly what my husband just said, he felt like he lived in a fog bank.. he had a lack of comprension... some times he could just not get what was in his brain to his hands.. He could not some times understand what I said to him.. and their were times when things could be sitting right in front of him and he could not see them till I pointed out the object of his searching..
sounds to me like the Candia has hit your brain.. you may have already had the candida.. the Antibiotics just pushed you over the edge !!
