Well, I don't think I can add to anything that you haven't tried but I am having strong reactions to organic sauerkraut. I think the good flora should strengthen the immune system and hopefully give it a chance to focus on the more pressing issues instead of being overwhelmed. Exactly what most of us feel here. Water kefir isn't a bad way to go which is good if one doesn't want to try the milk kefir. There is a roadblock for me as far as why the parasites are still here. I'm not sure if it's immunity related, toxicity, nutrition, stress or variations of them all. All I know is that I have taken a considerable amount of drugs and while some of them worked I should've gotten better results so far. Today the discovery is organic sauerkraut and taking a 4000 I.U.'s of vitamin D with MK4 (a strong reaction there too). In the past I thought I could starve them out and win the war of attrition. But, that approach hasn't worked for me thus far. I'm sorry you've had such difficulties.
