Thanks - read my new post - I chickened out of the chelation idea and recanted to the parasite. I have SF-722 to try but again don't want to try too much at one time. The time right now has been reinstated to the parasites. But I will keep that in mind if yeast becomes a bigger issue. Hard to tell what is causing what. I have to remind myself to go slow and tackly one thing at a time. Patience is a virtue - I had it years ago but have lost some as sickness took over. I feel like I've felt crappy for so long that now I deserve to be healthy and i do but not right away. It's a process - you guys are going to have to remind me of that ever so often.
