Every since I can remember I've needed to add some salt to my food at every meal, to the point where spending the day at a friend's house where they did not have any salt
would make me ill. When you're planning your schedule around how long you have to go without salt, you know it's pretty bad.
Of course, they told me I had just "developed a taste for it" and that it was bad for me and I needed to just break the habit.
When I became bedridden my need for salt skyrocketed--I would eat with salt right next to me and add it continually to my food as I ate, and my water had added electrolytes as well. I tried decreasing it a few times, and it always made me worse. At one point I tracked my sodium intake for a day, and discovered that I was consuming well over twice the absolute maximum amout of daily sodium recommended by the "experts" every single day. But around that same time blood tests revealed that my sodium levels were "normal". I found that fascinating.
As I have become less bedridden, I have found I no longer need the electrolytes in my water, except on occasion.
In the past few weeks I've been experimenting with salt. I find that the more I "force" myself to rest the less salt I seem to need. When I spent a couple days doing nothing but resting even though I could have been doing things around the room, I could begin a meal without any need for salt, but within about five minutes I would begin to need it, and more and more as the act of chewing my food exhausted me. I found that if I stopped eating the second I felt the need for salt and instead went back to resting (lights out, eyes closed, not moving, breathing deeply and slowly) then I could get by on this routine without feeling the need for any added salt at all. However, with this approach I couldn't eat enough--eating is just such an exhausting activity. So now I'm back to salt on my food.
Anyway, I'm pretty confident in my body's indications of whether or not I need salt and in my own awareness of it. I'm glad to see I'm not the only one who has experienced this relationship with salt, because it seems like all I hear about is how everyone should always be decreasing their consumption of it!
