I so agree with you HOW,
To get hydrated, one need salt; unless one want it to be flushed down the loo.
My mother didnt get well until I almost forced her to take salt and iodine; she had the opinion that salt was her enemy (kidney stones, lupus like inflammation; probably would have had the latter diagnosis if she hadnt had the rants at the doctors.)
She used to drink loads of water, type 3 liters daily in her tiny body.
Diarrhea, cramping, running to the loo all night etc.
All well now because of those two little supplements.
