If you come to the conclusion that you want to move forward with the fungal die off, but are worried about the side effects. I would recommend activated charcoal to get through the tough die off.
One cool thing that the S.Boulardii did for me was get rid of my ingrown toenail. I have had for as long as I can remember and I always suspected that it was yeast related because it would flare up if I ate too much sugar. I haven’t had a flare up since xmas. While I was taking S.Boulardii it began to itch like crazy, it drove me nuts there was no way to itch under my toenail. Soon enough it cleared up and I’ve not felt anything since.
