hmmm... ya know, I think it would be interesting to get the stuff that comes out analyzed to make sure it's candida and not friendly flora. At a certain stage, candida looks a lot like acidophilus. It'd be nice to get confirmation that you're not actually getting rid of the friendlies. Is that too weird a thought? :)
What about making you own kefir, or the Molkosan? Think that's helping?
