I guess many have seen twitchytoes's posts about salty goo.
After personally experiencing something like that I decided to try to find out what might be going on, away from all the obvious labels.
It seems that chronic dehydration will cause this but often it cannot be relieved just by drinking water. Some seem to think deficiencies of b12 or zinc might exacerbate the problem. But it's also apparently something you can get with an electrolyte imbalance.
Here's what I have read. Coconut water is nature's way of helping to restore electrolyte balance. Coconut water has even been used in emergency battlefield situations when regular remedies were unavailable.
I don't know if this will help TT but might make interesting reading for some of you.
