Before you spend any more money, realize that the missing ingredient is not supplements or probiotics, it's time. (sure supplements help a lot but you have enough at this point!) I think spending money on tons of expensive antifungal in particular when you haven't fixed 'leaky gut' is a waste of money. actually, the best anti-fungal I've used was liquidizing half a pomelo and drinking.
First thing I'd recommend doing is the pysillium and Bentonite shakes. It's highly recommended and it does help. Your gut needs to heal and icanard to do so with to s of candida.
Second, have you read the old shelly post 'how to increase digestion'? It advises no water 30 minutes before a meal and 1 hour after. Please go read this post: //www.curezone.org/blogs/fm.asp?i=976130
. There used to be a link Shelly posts at the top of the forum page so I'd like to think people respected her advice.
Last diet. From my experience, the candida diet helps digestion. When I broke the diet, my digestion halted and I became constipated. This is normal. It takes a time for your gut to heal.
