Yeah, I definately think the no carb diet is crucial at the outset.
I'd be more than happy living with the results of a no-carb diet alone.
A long time ago I did it a few times, but of course I slipped back to carbs each time (even small amounts screwed me up), and then the thought of going through the horrendous die-off again stopped me from doing it again untill now.
I've made kefir and took it every day for over a month and it didnt do much for me at all, no die-off or anything, same with sauerkraut.
If I remember right, I read that pharma drugs like Nystatin, Sporanox(?), need to be rotated inorder for the yeast not to build up a resistance.
