That's quite a large regimen.
Sounds like you're killing off any good bacteria that might be trying to establish itself. Remember, Candida is an imbalance of good/bad flora. We want to reach an equilibrium, not destroy EVERYTHING.
I would drink more Kefir.
Brewing you're own Kefir is recommended because it contains more strains of good bacteria compared to store bought junk.
Also, try drinking 2 tablespoons of Apple Cider Vinegar (I've heard the flora loves it and it helps me) daily: one in the morning before breakfast and one before dinner.
Adding Lugols solution may help as well. It has helped me tremendously.
