This is not an answer to your question, sorry, but I saw your name as I was browsing by, and wanted to ask you if you have ever tried the Rejuvenative Foods saurkraut or vegi delight cultured veggies. Stanna has brought herself back from the brink with them, and I read good stuff on Healthy Awareness from folks who were in pretty bad shape fidning new life with them, so I tried them. I find them wonderful, and the last remnants of white tongue were gone after using them for not even a week. Yesterday, I hit a landmark in that I actualy had a day where I felt normal. I have had plenty of better/worse, but "normal" - that was a very interesting thing to experience! Maybe they would help with your tongue issues?
