My mad Google-fu skills found this interesting
article.
I particularly dig this part:
"If stress and adrenal exhaustion are causing your salt cravings, try eating food that are high in Vitamin C and Potassium.
Foods High In Vitamin C – Citrus, Pepper, Broccoli
Foods High In Potassium – Apricots, Bran Wheat, Raisins, Figs, and Baked Potato With Skin"
You could try it! I know that a lot of times cravings are because our bodies are short on a nutrient. For instance, during my TOM I always crave Iron-rich foods like raisins, spinach and beef. I don't usually crave salt myself, but I take Vitamin C supplements every day and my diet includes a lot of foods rich in both C and Potassium.
And if you don't like any of the listed foods there are other foods that are high in those nutrients. I know kiwi has a lot of C and bananas have a lot of potassium.
But all that said, I don't know if I'm even on the right track. Just suggesting what I would try if I were in your shoes.
I hope you figure it out. Good luck!
