Hey there. Thanks. Yeah I have to watch my salt actually because I have adrenal insufficiency and if it gets too low (which it does often in AI), it can be dangerous.
I can't have too much either though, because it makes me feel unwell in a different way (irritated tissues?). But yeah at the start of my adrenal issues I used to take HEAPS of salt and its the only thing that kept me upright along with licorice root (which increased my asthma/allergies but it worked).
I have been trying salt water during the heart eps, and it helps, very temporarily. Im not sure what is going on with the heart to be exact.
