i've always been very aware of my body and when i take the first dose of Epsom Salt with each and every flush i've done, i've been aware of my eyesite sharpening suddenly, my brain is like a fog lifts, i suddenly feel my blood rushing thru my veins. i have no doubt that while all this is going on, my liver ducts dialte too.
