I would stop the psyllium husks immediately, please read the post titled; “The Site’s Suggestions” located above. Sounds like you have…
Another post worth checking out is this one (proper and safe cleanse):
Your symptoms sound like typical candida symptoms.
To answer your questions:
1) I have no idea.
2) I would consider doing the proper cleanse treatment able mentions. All of the other supplements should be taken during the die-off stage of the diet. Consult a naturopathic doctor for the best plan for you…especially if there is too much information to handle on the forum. Naturopaths come like the colors of the rainbow, so finding a good one may be difficult. The guidelines and help/info provided on the forum is typically superior.
3) I would wait to have supplements until you start the diet and the die off symptoms start…be ready to feel pretty bad for a few weeks or longer.
Remember it can take as long as 6-12 months to fully recover from candida.
