Thx for the advice, but

The anaesthetic worked fine

Linus Pauling himself took 18g a day, and he talks about the supposed evidence for kidney stones in one of his books

I've never heard about its effects on iron, but my iron is low anyway and I've struggled on and off with anemia for several years. My ferritin is very low. So no worries there.

It's great stuff. Pauling knew what he was talking about. I don't always take such large doses though, usually it's 9 grams a day. Less than that and I'm coming down with cold after cold.

Yes it can give you diarrhoea in high doses; that's when you stop at the dose you're at and pull back a bit. It's called taking it to bowel tolerance. After getting mercury in my system I figure it's not a bad idea to try to flush some out, but I haven't even got up to bowel tolerance.

There have been so many bogus studies and so many misquotes, so much misinformation, that this incredible vitamin is overlooked by many people even though it can help cure things ranging from the common cold to cancer. It should be in every IV drip at hospitals.
