Bex, often feeling worse means that parasites or candida are being killed, or that your body is detoxifying. I don't buy the argument that people get worse while taking in more sulphur. How people feel temporarily and whether they are healing are two very different issues. With illnesses that give the body a toxic load(mercury poisoning, candida, parasites) one typically needs to feel worse temporarily in order to heal. Perhaps those that have unbearable short term symptoms are overdoing it, and using too large a dosage?
