Am I Missing Something?

[pll]

I wonder if anemia could cause salt cravings, too...?

Don't think so. I think one should rule out the simplest explanation first: mild dehydration and loss of electrolytes through sweating. The fact that 32 oz of Gatorade made Bethany feel a lot better would suggest that some experimentation with different sources of electrolytes and/or maybe savory riding treats while riding is in order. [BTW, I also find Gatorade too sweet and cannot drink much of it.]

Adrenal problems can cause salt cravings, but they also come with a host of other unpleasant symptoms... then there is pregnancy...
