I do sea salt dissolved in water with vitamin C too, but it's for my adrenals. I do about 1/2 to 1 tsp of sea salt per glass of water three times a day. I looked at the Salt/C protocol to see how similar it was to what I was doing, and it's much much higher amounts. The reason for the salt is to kill pathogens.
I have also heard of people having problems with the Salt/C protocol and feeling much worse, which I think is not reflected in the survey. I've asked Ken to update that page a couple of times over the past couple of years, but he hasn't. I don't go over to the CFSFMExperimental board much anymore for that and other reasons.
