Crazy amount-? I take 9g a day, in divided doses. I used to take less, but this is what seemed to be required for me not to be ill all the time. I've been taking this amount for months and it's been working well. I agree, diarrhoea can occur when you take vitamin C to bowel tolerance -- I've done that when I've been ill. I don't think my vitamin C intake has suddenly decided to bite back at me however.

I seem to have been OK for a while, so it's possible I just had a touch of a bug. You just never know do you. Something else seems to come along quickly enough. I've felt awful today and I've decided to sucker into buying this little trinket which is claimed to be a "harmoniser" that protects you from harmful EMFs. You do anything when you feel bad enough LOL.
