I have read your various posts on cleansing and flu shots, etc.
You might want to consider using a very natural product, probiotic - lactic bacteria. It is with us since the day we begin to drink mother's milk.
Not only will probiotic help overcome a lot of digestive problems but will also boost your immune system. With it you no longer have to rely on flu shots and introduce foreign bacterium/viruses into your body. However, make sure you use a very good, preferably "live" multi-strained probiotic!
