I now put salt on the appropriate meals, if I get lightheaded, I just grind some salt in my hand and follow it with water. Always feel much better. As a young man in Southeast Asia, we took salt tablets. When I did, I felt like I just got an energy burst. I've read several articles on salt intake. One thing I've learned is nobody seems to agree. I usually go with the answer that makes sense. My experience is few doctors use logic. Maybe its liability, they don't want to step outside the box. I control my BP with supplements. Very few side effects.
