Magnesium is amazing stuff isn't it? Try taking an Epsom Salt bath for 20 minutes and then try to eat something even remotely bad for you. My body says stop eating this crap now and gives me a reaction. Why would your eyesight get better after a flush and then worse? Because when you do a flush the liver and g/b are flushed of toxins which then allows the body to drain more toxins into them that they couldn't before. Think of a sponge, it can only hold so much water no matter what. If you squeeze it but it is still sitting in water it will fill up again. This is what your body does. Eventually, your body will drain the toxins out. Epsom Salts , at least for me when I bathe in them, let me know what the toxins are. I can no longer eat cheese or any dairy products without a negative reaction. The reaction gets worse after every new epsom bath and it is helping me stop the dairy, but it is not easy. But it is not easy having my throat close up and phlegm out the ying yang either. Good luck!!
