Going trough die-off can be very difficult...it can even make you want to abandon the program even if you know that you desperatly need it!
One thing you have to know, is that die-off is a sign that what you are doing is working but it also means that all your capacity to detoxify have been overwhelmed..
So by cutting back on antifungals is the first step until you feel better.
The other one is supporting all detox channels: liver, skin, colon, kidneys and lungs.
The skin beeing the largest organ, use it through "detox bath": it is amazing! You just have to take a regular bath and wait until your forehead is starting to sweat: then count at least 15 minutes. Do that everyday! (it seems ridiculously simple but it works!)
Then you have to find a way to go to the washroom:psyllium,magnesium, flax seed oils, herbal teas with cherry stems or artichoke* (especially good if you are constipated because of your liver ...which is possible because you have been sick for a long time). colonics done by professionnals can also be very very helpful.
Support your liver with milk thisle ...it is a very good herb that helps to detoxify, protect and regenerate your liver cells. It is very safe. (if you have trouble sleeping do not take it at night and also start at very low dosage to see how your body can handle it.)
Drink a lot of water...of course!
Molybdenum also helps a lot with brain fog and anxiety but again low dosage.(if taken at high dosage could give you a gout crisis! You do not want that!)
Already with the baths you will see a major difference!
