In the morning, when I wake up within 2 hours of I do not take any salty content then feel a mind headache. If I was able to take even a pinch of salt either in the form of herbal tea, or in sprouts or salad, I can stay active till 4 or 5 hours without breakfast after waking up. Even I can do fasting , even a single vrat. Because I feel weakness and less energy without if I do not take salt. I do not eat any grains that will work but in fasting I need to take salt. I can't do that even though I got sick the next morning so I avoided fasting. Is there any test needed or is it how my body manages sodium.
