Managed to heal most of the gastritis using cabbage juice and a Vitamin U supplement (Gastrazyme, which is basically the goodies from the cabbage juice without the sugars), but the nausea and dull pain haven't shifted completely - in fact the nausea has got a little worse. Seriously suspect some form of parasite or bacteria are the root cause here, so I've just started Protocol C (10mls of 3000 ppm CDS in 1 litre of water, drink as 8 - 12 doses a day). Mr Kalcker recommends between 3 - 6 days for gastritis, so I'll update this thread in around 3 days time, my thanks again to everyone who has contributed so far.
