Well, of course it depends on the strength of the particular kefir, but as I’ve told you good folks before, the beneficial bacteria is going to be the final cure of your infestation, and without it, the time for healing would certainly be a lot, LOT longer – if ever. The results can also depend on the amount of flora that you already have in your system when you drink the kefir.
Just don’t overdo it with the kefir, as in drinking too much in one day or at one time. It can have the same effect on the Candida as an extremely powerful antifungal and create strong die-off symptoms.
Congratulations on your new find.
