Kat,
I also had salt cravings real good and low blood pressure all the time. I never have had a passing out experience, but have come close to it. I usually eat cheetos, or drink gatorade to pull me out of it or salt my foods real good. I switched my salt to sea salt and I feel this enhances the taste of my foods more. My heart will race, but I take inderal for mitral valve prolapse and that helps calm my heart rate down. With out it, it can go up to 140 and that’s about all I can tollerate. It really helps regulate my heart beats and makes me feel normal. -Julie
