Drinking water doesn't quench my thirst - solved with more salt?

There were several occasions when I drink water where my thirst does not go away. For me this is not a consistent problem, so I do not think it is diabetes (also I don't have any of the other symptoms of diabetes). After searching online, I found a few articles about not having enough salt.

So I tried this option. The primary reason is that I do have a very low sodium diet. When I cook, I do not use any salt, pepper, or other spices. At most, I use some oil but mostly to keep the food from sticking. Otherwise, I boil-fry most of my food. By boil-fry, I mean I just use just enough water to have the food stick to the pan... so I guess I basically steam my food or stir-fry with water. Anyways, the point is that I don't consume a lot of salt. I also don't eat out a lot. When I do, most outside food tastes salty too me.

I also drink a lot of water consistently so it is kind of odd that there are times that the quench does not go away. At first, I drank soda. One can or half bottle is enough to remove my quench for the episode. Now I keep energy drinks around, and that works just as well. It has been a while since the last I have had this issue (I just remembered to share this point only because the energy drinks are still sitting in my cabinets). I speculating that I have not had this problem for a while mostly because I have started to use some salt in my foods.

Anyways, this is my personal experience and experiment into the matter. I have also been exercising more regularly, averaging almost 5 miles a day. That may have a factor but I haven't found or felt like it contributed or helped with the problem.
