Rob, the book "Adrenal Fatigue: 21st century stress syndrome" by James Wilson has some good guidelines on diet and lifestyle changes. Granted it is written for those with less severe manifestations of adrenal deficiency, but nevertheless, the diet and lifestyle advice woudl be pertinient to you as well.
Pixie is right that we need to stay hydrated, but I'm not sure of the potassium. Some of us tend toward having high potassium, but low sodium, and it would be worthwhile to have electrolyte levels (sodium, potassium, etc) monitored until you are sure you are taking care of those properly.
The reason for the high potassium/low sodium issue is that the adrenals control the ratio of sodium

otassium in the blood by producing aldosterone. No aldosterone or low aldosterone causes loss of sodium and retention of potassium. If you are one of those people that animals tend to follow around, you may fit this scenario. (i.e. dogs lick you more than others livestok have a tendency to lick you...thye do this--seriously--because they are craving salt and we tend to lose salt through sweating, so we taste good to them.)
As for water...8 glasses a day (approximately a half-gallon or two liters) is a good start. I find that I need more than that, especially if outdoors alot or if I am more active.
In my case, I have to take in extra sodium and not pay much attention to potsassium levels as a recent blood test put both at the middle of their lab ranges.
Many of us have lower than normal or at least low-normal cholesterol. Since the adrenal glands use cholesterol as a building block for some of their products, it is important to make sure that the cholsesterol levels dont' go too low. that may sound contrary to all that you read, but cholesterol too low can be as bad as high cholesterol.
Hope this helps!
