That might be one to mention to your doctor actually. It shouldn’t be anything too concerning but it may be indicative of a deficiency in some nutrients or mineral.
My doctors got very concerned when I mentioned that I disliked the taste of salt. Not just salty foods or bacon but just the weird mineral and acrid taste of salt. Better now but still not a fan.
That your body does want a different sodium pairing is interesting.
Do you drink a lot of electrolyte drinks like Gatorade?
I was actually trying to express the same sentiment to my wife about her grandfather just this morning. Less crudely but also less eloquently.
