In my experience that is totally detox. By all means do the salt push, or the potassium chloride push!!! Make sure to take the vitamin C and some selenium and drink water! You kidneys are coping with a lot of toxin outflow. Help them.
I have found the chloride pushes help with the emotional detox as well. Toxins are chemicals that make you feel bad - get them out and the bad feelings often go with them.
