Leaky gut is a definitie setpstone. NO PROBIOTICS with leaky got so I am glad to hear you have stopped the kefir. Marshmallow root and plain water enemas. I have had it a long time ago, Like you doing daily enemas - it's been a while do I forgot what I did, but I wrote recommendations on my blog, you will find them there: //www.curezone.org/blogs/fm.asp?i=976162
If I were you I would not worry much about undigested veggies, they are full of fiber and they act as a brush onto the intestinal lining... dragging down the culprit. I would simply take mint tea to help with digestion and vitamin A + vitamin B complex to help at the source.
Now you first one to prioritise the leaky gut and then the next step will be easier.
