If you have adrenal fatigue, your sodium can be low no matter how much sodium you consume. ( at least in later stages).
If your Aldosterone is low, you will now retain the sodium. I'm in that state. I drink a ton of water with 1/4 teaspoon in each glass, and still I'm dehydrated.
Dr Lam has me on 600 mg of pantathine right now. I was on 300mg for a while.
