Nah, rather to have it being isotonic to the blood serum, as the wikipedia article puts it. (I guess that spoon per pint thing followed from there.) When it comes to ingestion the exact percentage isn't that important, but that's the level the body needs to maintain, so it's a good starting point for the kidneys to do the rest.Yeah get a big glass (about 500ml) and add a teaspoon of salt to it. I think the 0.9% comes from a teaspoon of salt in a pint glass, which I make to be a solution of 0.868% (so 0.9% on rounding), but in a 500ml glass that becomes 1% dead, but I reckon that's close enough. If you're having trouble keeping down food, you can also add a teaspoon of sugar to it as well. I have had to do that in the past.
