Re: [pct-l] Dehydration, Salt depletion, blisters and swollen feet, loss of appetite

Lots to think about here. Nice to believe my ERT may be good for
something! I don't know of any way to monitor electrolyte level. Urine
color is about hydration not electrolytes. Can you take in too much salt
or potassium? I will be taking potassium as part of daily supplements
but am real aware of the kind of weakness that people talk about and
believe it to be a combination of lack of water and electrolytes. don't
have any great wisdom for solutions. Just honor the quality and variety
of information that comes across these emails. Thanks Joanne.
