I got a cough and a cold as die off when I first started. It seemed to be that the candida was trying to come out through mucus in my chest and head so I did everything I could to get it out. I dont know how much of a difference it made but you never know.
I found that lemon drinks and the liver flush drink with ginger and garlic brought phlegm up almost immediately and I also used a facial sauna / steamer type thing with vicks to bring up more.
Hope you feel better soon 🙂
