Sorry to hear about your experience. And I hope you feel better soon.
It sounds to me like you might have broken up a biofilm. Braggzyme broke it up and the Undecylenic killed it, maybe? I experienced something similar with raw garlic.
Big die-offs are unsettling and always make me question whether I've done something wrong, when it's usually the opposite.
Good bacteria do form biofilms, but Candida biofilms are like sci-fi creepy and can do bizarre things. I don't even like to think about them, and haven't seen evidence of them on myself in a couple of months, thankfully.
But the Serrapeptase and Natto are both known for breaking up Candida biofilms. So you may have just done a very good thing. Hopefully, it's a one-time-epic-die-off. Maybe try it at a lower level after you feel better?
**(I later remembered the Natto is a blood thinner and might explain the heart issue. I'm thinking you might want to avoid it. Maybe try Serrapeptase w/o Nattokinase.)
On the fruit issue, I think you're right. I feel like anything w/ a remotely high glycemic value stops/slows my progress. I got so confused about what to eat, that I planned out 5 small meals I know won't set me back, and eat the same thing every day w/ only a bit of variation. Boring, but it works.
On the probiotics issue, my philosophy is to keep taking them, but not at the same time as antifungals. A couple of hours apart. My thinking is that I want to have them there all the time to re-colonize if new territory opens up. And it seems to be working.
On the permeability issue, Lactobacillus GG is supposed to help form a barrier and reduce permeability. Try a search on that.
I just started the GG, so I'm not sure if the claims are true. They have supporting studies, but you know how that is.
The biofilm protocol would probably disturb the bacteria and not the yeast. I think Dvjorge is right. The Candida Biofilm is fibrous and I think it's pretty susceptible to Serrapeptase, Freeze-Dried or Raw Garlic, and the Undecylenic Acid among others (but I've seen a few posts lately where their strains are immune to Undecylenic)...Just not sure you need the protocol.
I'm wary of the EDTA in the Interfase. But it's an interesting product. And I'm a big fan of digestive and systemic enzymes. I feel like they're helping me a lot.
Are you sure you have Mercury poising? That's an area where I'm skeptical with some of the product claims. I've read that true Chelation needs to be done w/ medical supervision and that removing the source is the best way to handle it. Your body will take care of the rest. But that's just my take.
Well, I hope there's something in here that you find useful and I hope you are successful. 10 years is a long time to fight.
