Potatoes or rice almost every night of the week!? I'd say your efforts have been worth it!
I've been having a few issues with my lower back and eye just recently. I didn't want to be too bothered by it all so I avoided this site and researching to think about it as little as possible.
I added way too many things at once. Banana starch, few diffrent prebiotics and a bunch of different probiotics.

Hard to pinpoint what caused my issues but I gave all of the pstarch etc. a rest for roughly a week. I'm back on the pstarch(3tbs) and am only adding tiny amounts of bsatrch. This article is what got me back on the train http://freetheanimal.com/2014/05/resistant-problems-ignorance.html

I thought the same about Borax and it's anti-fungal properties along-side pro/pre biotics and stopped for a bit. Even though I'm really starting to think that I should get in there with the anti-fungals and natural kleb killers BEFORE I go blowing my $ on expensive probiotics that won't stick.
I'm pretty sure it was CRV that posted this elsewhere but they mention k.Phneum specifically where it says,
"Harmful Bacteria Protocol"

Any opinions on the biofase listed in the same article?
