Holy shit, me too.
Regarding this potassium paper, it's interesting that it primarily concerns itself with sodium and potassium intake. I don't know that any reasonable change to my intake could have overcome the effects of aldosterone overproduction, but wouldn't the recommended changes to your diet depend on measuring your current balance?
During the work up I had to drink 18g/day of the foulest liquid ever to get my K levels high enough for the adrenal vein sampling to be valid.
