There is a gentleman called Chris Wark, 'Chris Beat Cancer', who swears by this protocol. He claimed it was instrumental in curing his cancer, and has never had a cold since..... I half heartedly tried it once, before I knew I was in this mess, and may well revisit. I still have heaps of Vit C left over.... The only thing I found was that as it's acid, it was destroying my teeth - I could literally feel it stripping the enamel. Thoughts on how to get around this would be welcome.
