There are many forms of discharge. My wife and I have had various types of discharges - her more strongly than me. My immediate family members have also had various discharges when they have come to visit for several weeks and having to eat our food.
The most common first discharge symtoms that I have noticed are mucus discharge. Lots of mucus coming out of the body via the nose. Two sweating and almost fever-like conditions. These have been obvious in my circle of friends and family. My wife has had more severe ones such as dark patches on her skin, scaly skin, rashes etc., though none too serious and all have more or less disappeared after a while.
Discharging is an individual phenomenon. We own a restaurant and do cooking lessons, all on macrobiotics, www.naturalgarden.ca check it out.
Many of our customers and clients have had discharges too, of various magnitude and kind.
Let your body guide you. Be strict if you want to be, don't be if you don't want to be strict with your diet. Do what you can do and don't push it. Do what you are comfortable with and nature will take care of itself.
